If your paycheck does not match your hours, you need more than a memory — you need a verified, timestamped record of your labour. This guide tells you exactly what to document, how to calculate what you are owed, and what mistakes erase otherwise valid wage recovery claims.
Wage theft is the most common crime against workers — and the most under-reported. Off-the-clock work, shaved hours, forced unpaid breaks, and misclassification cost workers billions every year. The workers who recover their money are almost always the ones who documented it.
This guide covers the complete documentation process for wage theft and unpaid overtime — from building a personal hours log and identifying what type of wage theft you are experiencing, through preserving the specific records labour boards and courts need, and avoiding the mistakes that routinely cause valid claims to be dismissed or underpaid. For workplace harassment documentation, see the companion guide: How to Document Harassment at Work.
Common Patterns of Wage Theft
Wage theft rarely looks like what the name implies. It is usually structured to be deniable — framed as a policy, a rounding practice, or a classification decision — rather than an overt refusal to pay. Recognising the pattern you are experiencing is the first step to documenting it correctly, because each type requires different evidence.
Off-the-clock work — being asked to perform tasks after punching out: closing duties, cleaning, restocking, end-of-shift paperwork, or equipment checks. Also includes being required to arrive early and begin working before the official start time without that time being recorded. This is the most common form of wage theft, and it is usually transmitted verbally or through informal instruction — which is why contemporaneous notes of those instructions are critical.
Time-shaving and rounding manipulation — employer timekeeping systems that round clock-in times forward and clock-out times back beyond what any neutral rounding policy would justify; supervisors who manually edit timesheets; software that automatically truncates minutes below a threshold. The gap between what the system records and what your personal log records is the evidence.
Unpaid or forced short breaks — automatically deducting a standard lunch or break period from every shift regardless of whether you actually took it; requiring you to remain on-call or available during a deducted break period; interrupting breaks for work tasks without recording the interruption. In most jurisdictions, a break during which you are required to remain available or to work is a compensable break.
Misclassification as independent contractor — designating a worker as a contractor or freelancer to avoid overtime, benefits, and employment standards obligations when the actual working relationship has the characteristics of employment: fixed schedule, employer-controlled methods, employer-supplied equipment, and integration into the employer's regular business. Misclassification is one of the highest-value wage theft claims because it covers every week of the misclassified period.
Illegal deductions — charging for uniforms, tools, or equipment required for the job; deducting register shortages or breakages from wages; charging for training; withholding wages as a security deposit. Whether these deductions are legal depends entirely on your jurisdiction — in many, any deduction that reduces wages below minimum wage is prohibited outright.
Unpaid training and onboarding time — mandatory pre-employment training, orientation sessions, shadow shifts, or trial periods for which no pay was received. In most jurisdictions, if the employer required the attendance and benefited from the work, the time is compensable regardless of how it was labelled.
Tip theft and tip pooling violations — managers or supervisors taking a share of tips contrary to law; tip pools that include ineligible employees; deducting credit card processing fees from tipped workers' earnings beyond what the law permits. Tip records — both your own and any employer-produced point-of-sale records — are the primary evidence here.
Unpaid overtime — failing to pay the overtime premium for hours worked above the threshold (typically 40 hours per week in the U.S., 44 in most Canadian provinces); misapplying overtime exemptions to workers who do not legally qualify for them; calculating overtime on base pay only while excluding regular bonus or incentive compensation from the calculation base.
Building Your Personal Hours Log
A personal hours log is the foundation of any wage theft claim. When employer records are inaccurate, incomplete, or simply do not exist, a contemporaneous personal log — one kept in real time, not reconstructed — is accepted as evidence by labour boards and courts across every jurisdiction covered here. The key word is contemporaneous: a log written each day as you work it carries legal weight that a log reconstructed from memory does not.
What to record in every entry
Date and day of the week — record both; discrepancies in the employer's records sometimes show on specific days of the week, and the pattern becomes visible across your log.
Actual start time — the moment you began performing any work-related task, including arriving early at a manager's direction, starting equipment before the official clock-in window, or attending a mandatory pre-shift meeting.
Actual end time — the moment you stopped performing any work-related task, including off-the-clock tasks after your official punch-out. Note any verbal instruction to continue working after punching out, including who gave it.
Break periods actually taken — the actual start and end time of each break taken, and whether any break was interrupted or shortened by work tasks. If you worked through a break that was auto-deducted, note it explicitly.
Total hours worked — calculate the total from your actual start and end times, not from the employer's record. This is the number you will compare against your pay stub.
Employer's recorded hours — note what the official system shows for that day, where you can see it. The gap between your number and theirs is the evidence of shaving.
Any off-the-clock work and who directed it — a brief factual description: "At 5:47 PM, after clocking out at 5:30, supervisor [name] asked me to finish [task]. Completed at approximately 6:10 PM. Not paid."
Wage rate applicable that day — if your rate varies by shift type, day of week, or role, note which rate applied. This matters for calculating the correct overtime base.
Storage rules
Store only on personal devices and personal accounts. Never use a work phone, work email, or any employer-controlled platform to keep your hours log. Employer systems can be accessed, edited, and deleted by management and IT. Use a personal phone, personal email, or a dedicated wage-logging app on a device you own.
Back up to at least two locations. One copy on your device, one in a personal cloud account (Google Drive, iCloud, Dropbox), and ideally a third forwarded periodically to a trusted personal email address. If your device is lost or damaged, your evidence must survive.
Never alter a past entry. If you need to correct or add to an entry, create a dated addendum. Edited logs lose credibility and can be challenged as fabricated. The addendum is expected and acceptable; the retroactive edit is not.
"A log written the evening of each shift is direct evidence. A log reconstructed from memory three months after a dispute begins is testimony. Tribunals treat them very differently."
Calculating What You Are Owed
A documented hours log only becomes a wage recovery case when you translate it into a dollar figure with enough precision for a labour board or court to act on it. The calculation has several components that must each be correct.
Step 1 — Establish your correct hourly rate
Your base rate must be at least minimum wage for your jurisdiction, applied to every compensable hour including all those you were not paid for. If you were misclassified, the applicable rate is also determined by your jurisdiction's employment standards — not the rate in a contractor agreement that the law may disregard. If tips form part of your compensation, confirm whether your jurisdiction allows tip credits to reduce the cash wage below minimum, and if so, whether those credits were properly applied.
Step 2 — Identify your overtime threshold and rate
Overtime thresholds and rates vary by jurisdiction. In the United States, federal law requires 1.5x pay for hours over 40 per workweek; some states set lower thresholds or higher multipliers. In most Canadian provinces, the threshold is 44 hours per week, though it varies. In the United Kingdom, there is no statutory overtime premium — but the total pay for all hours worked must not fall below the National Minimum Wage. In Mexico, hours worked beyond the standard 8-hour day trigger overtime at 200% (double time) for the first 9 extra hours per week, then 300% (triple time) beyond that.
🇨🇦 Quebec: Under the Act respecting labour standards, overtime is payable at 1.5x for hours beyond 40 per week. The CNESST enforces minimum wage and overtime standards. Confirm the current minimum wage and overtime rules with the CNESST or a labour lawyer before calculating your claim.
🇲🇽 Mexico: Under the Ley Federal del Trabajo, daily overtime beyond 8 hours is compensated at 200% for the first hour and 300% beyond that within the week. Weekly rest day work triggers additional premiums. Confirm applicable rates and thresholds with counsel familiar with your specific state and sector.
Step 3 — Build a week-by-week comparison table
For each workweek in the recovery period, create a row showing: total hours actually worked (from your personal log); total hours paid (from your pay stubs); the difference; the dollar value of straight-time pay owed for any unpaid regular hours; the dollar value of overtime premium owed for any unpaid or miscalculated overtime hours; and any applicable deductions that were unlawful. The table is what you hand to the labour board or a lawyer — it converts raw logs into a concrete claim.
Step 4 — Identify the recovery period
Labour standards limitation periods determine how far back your claim can reach. In the U.S., the Fair Labor Standards Act allows a 2-year recovery period (3 years for willful violations). In most Canadian provinces, the recovery period ranges from 1 to 2 years under employment standards legislation, with longer periods possible in civil court. In Quebec, the recovery period under the Act respecting labour standards is 3 years. In Mexico, the JFCA limitation period for wage claims is generally 1 year from when wages were owed. In the UK, unlawful deductions from wages claims must be brought within 3 months of the last deduction. Calculate your total claim from the furthest date your jurisdiction permits.
What Evidence to Preserve — and Where to Find It
A personal hours log is necessary but rarely sufficient on its own. The strongest wage theft claims pair a personal log with objective, employer-generated records that the employer cannot easily dispute without contradicting their own systems. Here is what to collect and where to find it.
Pay stubs — every one, going back as far as you can. Pay stubs are the baseline document: they show what the employer claims you were paid, for how many hours, and at what rate. The gap between your hours log and the hours on the pay stub is the quantified wage theft. Keep pay stubs in a personal location — printed, photographed, or forwarded to a personal email — from the start of your employment.
Timekeeping system records. Screenshots or printouts of whatever timekeeping system your employer uses — punch-in clocks, biometric readers, digital time cards, scheduling apps. Many workers do not realise they have a right to see their own time records. In the U.S., the FLSA requires employers to keep these records for at least three years. Request them in writing before they are altered or purged. Print or photograph your punches before clocking out if the system allows.
Schedules and scheduling software records. Screenshots of posted schedules, shift assignment apps (Deputy, When I Work, Homebase), and any messages about schedule changes. Scheduled hours are not the same as worked hours, but they corroborate what the employer expected you to be doing and when — and they show the minimum hours you were present.
Messages directing off-the-clock work. Text messages, WhatsApp, Slack, email, or any platform on which a manager communicated instructions to work after clocking out, to skip breaks, to arrive early, or to perform tasks without recording them. Screenshot and transfer to a personal device immediately. These are the most direct evidence of intent on the employer's part — a manager who puts "just finish this before you leave" in writing has created an admission.
Bank statements and direct deposit records. Your bank records show exactly what was deposited and when. For regular employees, consistent deposit amounts that do not correspond to scheduled hours help establish the pattern of underpayment across the entire employment period.
Industry-specific operational records. Different industries generate different corroborating records that the employer cannot deny because they produced them. In retail and food service, point-of-sale login and logout timestamps show exactly when you were actively using the system — if those times extend before your recorded clock-in or after your clock-out, they corroborate off-the-clock work. In logistics and warehouse environments, scanner activity logs, route completion timestamps, and delivery confirmation records serve the same function. In healthcare, patient charting timestamps and electronic medical record access logs show when you were working. Preserve any such records you have access to before your employment ends.
Witness statements and co-worker observations. Colleagues who observed you working off the clock, who were given the same instructions, or who can confirm that certain off-the-clock tasks were routinely required of your position add corroboration to your personal log. Note their names and what they observed in your log at the time. A lawyer can advise on compellable testimony if they decline to cooperate voluntarily.
Photographs of physical time records before submission. If your workplace uses paper timesheets or manual punch cards, photograph them before submitting — before any editing can occur. If you observe a supervisor editing a timesheet, note the date, time, what was changed, and who did it.
Reporting Internally and Escalating Externally
Before filing a claim with a government labour board, most jurisdictions require or strongly encourage an internal complaint first. Documenting that complaint — and the employer's response to it — is itself part of the wage theft record.
Make every internal complaint in writing. A verbal complaint to a manager or HR about unpaid wages is easily denied and leaves no record. Send an email to HR or payroll stating: the specific pay periods at issue, the hours you actually worked versus the hours you were paid, and the dollar amount of the discrepancy you have calculated. Keep a copy of every communication, including any response.
Request your own payroll and time records in writing. Submit a written request to HR or payroll for copies of your complete time records and payroll records for the period in question. In most jurisdictions, you are legally entitled to these. The request itself creates a paper trail. If the employer delays, denies, or produces records that differ from what you observed, document that discrepancy.
Document the employer's response — or non-response. What HR says, what payroll corrects (or does not correct), and whether any promised back-payment is actually made are all part of the record. An employer who acknowledged underpayment and then failed to remedy it is in a stronger liability position than one who was never notified.
Know your external filing options and their deadlines. If the internal process fails, file with the appropriate external agency before the limitation period expires. In the U.S., file with the Department of Labor's Wage and Hour Division and/or the relevant state labour board. In Canada, file with the provincial employment standards branch (e.g., Employment Standards Branch in BC, Ministry of Labour in Ontario, CNESST in Quebec). In the UK, file with ACAS for early conciliation, then the Employment Tribunal. In Mexico, file with the JFCA. Each has its own form, deadline, and process — confirm with legal counsel before filing.
Never resign or accept final payment without legal review. A final paycheque that includes language about payment in full, or a separation agreement that releases wage claims, may extinguish your right to recover unpaid wages. Have a lawyer review any final settlement document before signing. In the U.S., FLSA claims generally cannot be waived without Department of Labor or court supervision.
🇨🇦 Quebec: File a wage complaint with the CNESST (Commission des normes, de l'—quit—, de la sant— et de la s—curit— du travail). The CNESST enforces the Act respecting labour standards including minimum wage, overtime, and illegal deductions. The complaint must generally be filed within 3 years of the violation.
🇲🇽 Mexico: File a wage claim with the Junta Federal de Conciliación y Arbitraje (JFCA) or the applicable local labour board. General wage claims have a 1-year limitation period under the Ley Federal del Trabajo. File promptly — do not wait for internal resolution to run its course if the deadline is approaching.
Mistakes That Destroy Wage Theft Claims
Workers with valid, documented wage theft claims regularly lose or recover far less than they are owed because of avoidable errors. Each of the following has ended or severely damaged real claims.
Waiting too long to start logging. Every pay period that passes without a personal hours log is a pay period you can only reconstruct from memory — and reconstructed evidence is substantially weaker than contemporaneous evidence. Start the log on your first shift. The limitation period for wage claims is measured backward from the date you file; a log that covers the full limitation period recovers the full amount.
Relying solely on the employer's records. Employer timekeeping records are the records most likely to be inaccurate in a wage theft case. Courts and labour boards understand this. A personal log that can be compared against pay stubs — showing a consistent, documented gap over multiple weeks — is far more persuasive than an argument based on the employer's own figures.
Storing evidence on employer-controlled devices or accounts. Work phones, work email, employer scheduling apps, and company cloud storage are accessible to your employer's IT team. Evidence stored there can be edited, deleted, or become inaccessible after termination. Keep all evidence on personal devices and personal accounts exclusively.
Not keeping pay stubs from the beginning. Pay stubs are the primary objective record of what the employer claims to have paid you. Without them, calculating the underpayment gap requires the employer's cooperation or legal compulsion. Many workers discard pay stubs as routine paperwork — this is a major evidence gap. Keep every pay stub for the entire duration of employment.
Failing to document who gave the off-the-clock instruction. "My manager told me to keep working" is much weaker without a name, a date, and the specific words used. An employer will argue that no such instruction was ever given. A note that says: "On [date] at [time], [name], my shift supervisor, told me: 'Just finish the count before you leave — don't bother clocking back in'" is a specific, attributable instruction that is difficult to deny without calling the supervisor a liar in front of a tribunal.
Accepting a corrected paycheque without confirming the full amount. Employers who are caught underpaying sometimes issue a corrected payment that covers only the most recent discrepancy, not the full historical underpayment. Before accepting any correction as final, compare the payment to your complete wage calculation table and confirm that the entire recovery period is covered.
Signing any final payment, release, or separation agreement without legal review. A settlement cheque that includes language about full and final payment of all wage claims, or a separation agreement with a general release, may legally extinguish your right to pursue the remaining underpayment. In most jurisdictions, once signed, these are binding. Have a lawyer review every final document before signing.
Missing the filing deadline. Wage claim limitation periods are strictly enforced. Once the deadline passes, even a perfectly documented claim with irrefutable evidence may be legally barred. The deadline runs from when the wages were owed — not from when you discovered the violation or when you tried internal resolution. Confirm your jurisdiction's deadline and file before it expires.
Frequently Asked Questions
Can a personal log really be used as evidence in a wage theft case?
Yes. Labour boards and courts in Canada, the U.S., the UK, and Mexico all accept contemporaneous personal logs as evidence — particularly when the employer's own records are found to be inaccurate, incomplete, or unavailable. The U.S. Supreme Court held in Anderson v. Mt. Clemens Pottery Co. (1946) that when employer records are inadequate, workers may establish hours worked through their own evidence and reasonable estimates. Canadian labour boards apply a similar approach. What makes a personal log legally useful is that it was written in real time, is internally consistent, and can be corroborated by other evidence such as pay stubs or messages.
What is the most common form of wage theft?
Off-the-clock work — being required to perform tasks before the official clock-in or after the official clock-out without compensation — is the most widespread form. It is common in retail, food service, healthcare, warehouse, and hospitality environments. It is usually initiated by verbal instruction or informal culture rather than written policy, which is exactly why a contemporaneous log capturing those instructions — including who gave them and when — is the most important evidence in these cases.
My employer says I am an independent contractor. Does that mean I have no wage rights?
Not necessarily. The label "independent contractor" does not determine your legal status — your actual working conditions do. If your employer controls your schedule, your methods, and your tools; if you work exclusively or primarily for them; and if your work is integral to their regular business, a labour board or court may find that you are an employee regardless of what your contract says. Misclassification cases are often the highest-value wage theft claims because they cover every week of the entire misclassified period. Document your actual working conditions — schedule, supervision, equipment, exclusivity — as thoroughly as your hours.
How far back can I claim unpaid wages?
The recovery period depends on your jurisdiction and how you file. In the U.S., the FLSA provides a 2-year recovery period, extended to 3 years for willful violations. In most Canadian provinces, employment standards claims recover 1 to 2 years; civil court claims may reach further. In Quebec, the Act respecting labour standards provides a 3-year recovery period. In the UK, Employment Tribunal claims for unlawful deductions must be brought within 3 months of the last deduction, with tribunal recovery potentially capped at 2 years in a series of deductions. In Mexico, general wage claims before the JFCA have a 1-year limitation period. Start your log immediately — every week you delay is a week that may fall outside the recoverable period by the time you file.
What if my employer retaliates after I report wage theft?
Retaliation for reporting a wage violation is illegal in every jurisdiction covered here. If you experience any adverse employment action — reduced hours, demotion, schedule changes, discipline, or termination — after making an internal or external wage complaint, document the exact timeline between your complaint and the adverse action. That timeline is the core of a retaliation claim, which is a separate legal claim that compounds your employer's liability. The documentation practices are identical: specific dates, specific names, specific actions, and the causal connection between the complaint and the retaliation.
Do I need a lawyer to file a wage theft claim?
You do not need a lawyer to file a claim with a labour board or employment standards office — these agencies are designed to be accessible to workers without legal representation. However, a lawyer significantly improves your outcome in three situations: your claim is large enough to justify the cost; your employer has legal representation; or your claim involves misclassification, complex overtime calculations, or a retaliation component. Many employment lawyers handling wage claims work on contingency — they take a percentage of what you recover rather than an upfront fee. The free consultation offered by WORKWARS partner firms is specifically designed to help you assess whether legal representation makes sense for your specific claim.
