What to do if…
you discover your timesheet was changed after you submitted it

Short answer

Freeze the evidence first: save a copy of what you submitted and what it was changed to, then raise it calmly in writing to payroll/your manager asking for the edit reason and an immediate correction.

Do not do these things

  • Do not accuse someone of fraud or theft in a meeting or group chat while you’re still gathering facts.
  • Do not “fix it back” inside the system if that could look like you changed records too.
  • Do not sign/approve an amended timesheet or “confirm hours” unless you’ve checked every day and break.
  • Do not wait until the next payday if you can already see it’s wrong (delays make it harder to untangle).
  • Do not quit in the heat of the moment if you rely on this income—pause and document first.

What to do now

  1. Save what you can see right now (before it changes again).

    • Download/export the timesheet if possible.
    • Take screenshots showing the hours, dates, and any “last edited by / edited at / history” area.
    • Save any submission/approval emails or notifications.

  2. Write a quick “paper trail” message today (keep it factual).
    Email (or HR system message) payroll and your manager:

    • that you noticed changes after submission
    • the pay period/date range affected
    • the specific entries that changed
    • a clear ask: “Please confirm who changed it, why, and correct it (or tell me the formal correction process).”

  3. Ask specifically for the edit/audit trail and supporting logs.
    Ask payroll/HR to provide (or let you view) any timesheet “history” and related records (for example, clock-in/clock-out logs or supervisor adjustments) for the affected dates.

  4. Check whether pay is already affected (and capture that too).

    • If you’ve already been paid, compare your payslip to your own record/rota and note the exact shortfall.
    • If you have not been paid yet, ask payroll to confirm what hours will be used for this payroll run and the cut-off to correct it.

  5. Make your own clean timeline (for your own use).
    Write down: when you submitted, when you noticed the change, what changed, who you contacted, and their responses. Keep it factual.

  6. If you’re getting pushback, use the workplace process quickly.

    • If you’re in a union, contact your rep and share your saved copies.
    • If informal messages don’t resolve it, raise it as a formal grievance in writing (your employer should have a written grievance procedure).

  7. If they won’t share records you believe relate to you, consider a Subject Access Request.
    If you need your timekeeping/payroll data and the employer won’t provide it informally, you can generally request your personal data (including relevant logs about you) under UK data protection rules. Keep it narrow: dates, systems, and exactly what you need.

  8. If pay is being shorted and it’s not resolved, get outside help early (you’re not committing to a claim).
    Contact Acas for confidential advice. If you might need a tribunal claim, be aware there are strict time limits and raising the issue internally does not usually extend them—so don’t let the calendar run while you wait for replies.

What can wait

  • You do not need to decide today whether to take legal action, resign, or “go public”.
  • You do not need a perfect calculation of every minute right now—capture evidence, identify the specific changed entries, and get payroll to confirm what will be paid.
  • You can wait to write a longer statement until after you’ve received the first reply (unless payroll cut-offs are imminent).

Important reassurance

It’s common to feel shocked or angry when a record you rely on is altered. Taking 10–15 minutes to preserve what you saw and move the conversation into calm, written facts protects you and often gets a faster, cleaner fix.

Scope note

These are first steps to stabilise the situation, protect your pay record, and create a clear trail. Later steps (formal disputes or claims) depend on the details of your contract, pay arrangements, and what your employer says.

Important note

This is general information, not legal advice. Employment rights and the best route depend on your role, contract, and the reason the timesheet was edited. If you feel pressured, confused by the process, or the issue repeats, consider getting tailored advice (for example from Acas or a union adviser).
