Checking Your Shift Pay: What to Look For and How to Query It

Most people check one number on their payslip: what landed in the bank. If it looks roughly like last month, that is the end of the inspection.

For salaried work that is mostly fine — the number is the same every month and an error stands out. For shift work it is close to useless, because the number is supposed to move. Different hours, different premiums, different overtime, a swap that landed in a different week. When the correct figure changes every period, a wrong figure looks exactly like a right one.

This is not about assuming your employer is cheating you. The overwhelming majority of payroll errors are genuine: a shift entered under the wrong code, a swap that never made it into the system, a premium that did not trigger because the shift started eleven minutes outside the window. They are also, in a lot of cases, only fixed if somebody notices.

Keep your own record

You cannot check a payslip against nothing. The single highest-value habit here is having an independent record of what you actually worked, made at the time rather than reconstructed afterwards.

It does not need to be elaborate. For each shift: the date, start and finish, the position, and anything unusual — you stayed late, you covered a different station, it was a swap, it was approved overtime. Thirty seconds at the end of a shift.

The reason to do it at the time is that memory for this is far worse than people expect. Trying to reconstruct six weeks of shifts from a group chat and a photo of a rota is miserable, and it is exactly the situation you are in when you finally suspect something is wrong.

Read the lines, not the total

A payslip for shift work usually breaks into several distinct pay elements, and errors almost always live in one of them rather than in the headline figure. Work through them individually:

• Basic hours. Does the hours figure match your own count? This is the most common error and the easiest to check.
• Overtime. Is it there at all, and is it at the rate you expected? A frequent failure is overtime paid at basic rate because it was logged as ordinary hours.
• Shift premiums. Nights, weekends, and public holidays often carry a differential. Count how many qualifying shifts you worked and check the number of premiums matches.
• The pay period boundary. Shifts near the start or end of the period are where things go missing. A shift that crosses midnight can be attributed to either day, and the two are not always in the same pay week.
• Deductions. Tax code, pension contribution, anything voluntary. A wrong tax code will not usually be your employer’s error but it is still your money.

The errors that specifically affect traded shifts

If you trade shifts, there is a category of problem that people who work a fixed rota never encounter, and it is worth knowing what to look for.

The swap that was never recorded. Two people agree, both work the right shifts, and payroll pays them for the original rota. Depending on the shifts involved this can go either way, and the person who was underpaid usually only finds out weeks later.

The premium that moved with the shift. You gave away a Saturday and picked up a Tuesday. If the swap was not logged, you may still be showing as having worked the weekend — or, more painfully, the person who covered it is not.

The pickup logged as coverage. On some systems an extra shift recorded as covering somebody else is treated differently from an extra shift recorded as additional hours, and only one of them counts towards an overtime threshold.

The shift attributed to the wrong person entirely. Rarer, but it happens with informal swaps, and it is the reason having a written record of who agreed to what is worth more than it seems at the time.

All four are much easier to sort out when you can point at a specific agreement on a specific date. This is the mundane, unglamorous argument for settling trades somewhere with a record rather than in a group chat: not for disputes with colleagues, but for the far more common conversation with payroll six weeks later.

Check the periods where it is most likely to be wrong

Checking every payslip line by line forever is not realistic. If you are going to do it properly a few times a year, do it for the periods where errors cluster:

• Any period where you traded more than usual
• Any period containing a public holiday
• The first period after a rate change, a promotion, or a contract change
• The first period after your employer changed payroll or scheduling systems
• Any period where you worked a lot of overtime
• The period covering the start or end of the tax year

Raising it

If something looks wrong, the approach that works is unexciting and specific.

Work out the actual discrepancy first. “I think I am short” is much weaker than “I worked five night shifts in this period and I can only see three night premiums”. Payroll can act on the second immediately.

Ask rather than accuse. The first message should assume an error, because it almost certainly is one. “Can you help me understand this line” opens a conversation; anything sharper starts a defensive one, and you need their cooperation.

Put it in writing. Even if you raise it in person, follow up with a short message so there is a dated record. Pay corrections sometimes take a cycle or two, and the written trail is what stops it from being forgotten.

Check the correction. An adjustment on the next payslip should be identifiable as a specific line. If the total simply looks bigger, you have not actually verified anything.

Know where it escalates. If it is not resolved after two cycles, find out who owns payroll disputes — usually HR rather than your line manager, and in unionised workplaces your rep will have seen the same error before and will know exactly which system causes it.

Errors go both ways

Worth saying: sometimes you will find you were overpaid. The temptation to say nothing is understandable and it is generally a bad trade. Most employers can and do reclaim overpayments when they find them later, often as a lump deduction at a moment you do not choose, and a discrepancy you flagged is treated very differently from one you did not.

The point of all this

Ten minutes a few times a year, and a habit of noting what you actually worked. That is the whole discipline.

It matters more for shift workers than for almost anyone else, because the variability that makes the work flexible is the same variability that hides mistakes. A fixed salary is self-checking. A rota that changes every fortnight, with premiums and swaps and overtime thresholds layered on top, is not — and nobody else is going to check it for you.

Keeping your shifts, swaps, and who-agreed-to-what in one place makes this take minutes rather than an evening. That is a large part of what the calendar is actually for — not planning, which most people manage fine, but being able to answer “what did I work six weeks ago” without scrolling through a group chat.
