How to Spot and Fix Common Payslip Errors After Swaps or Overtime

A salary is largely self-checking. A schedule with premiums, swaps, overtime thresholds, and multiple sites is not. Errors cluster in predictable places. Knowing where to look turns a vague feeling that something is wrong into a specific, fixable claim.

Where the mistakes usually are

• A swapped shift still paid to the original person, or paid to you when you did not work it.
• A premium (night, weekend, holiday) missing on a shift that should have carried it.
• Overtime calculated on the wrong week boundary or at the wrong rate.
• A higher-paid role paid at your usual rate.
• Hours lost to an unpaid break that was not taken, or a break deducted twice.

These are the first places to check when the total feels low.

How to check efficiently

Work from your own record of what you actually worked. Match each shift to a line on the payslip. Confirm the rate and any premium. Then look at the overtime calculation for the week and see whether it matches the rules you believe apply.

You do not need to understand every payroll code. You need to see whether the shifts you worked appear, at roughly the right money.

How to raise the query

Be specific. “I think my pay is short” is easy to park. “Shift on Saturday 16 Aug 14:00–22:00 at Site B does not appear / appears without the weekend premium” is much harder to ignore.

Include:

• The date and times
• The location and role
• What you expected to see
• What actually appears (or does not)

Send it through whatever channel your workplace uses for payroll queries, and keep a copy.

Timing

Raise it as soon as you notice. Waiting until several pay periods later makes the correction harder and the trail colder. Most payroll teams would rather fix a clear, early query than reconstruct a month-old dispute.

You are not being difficult by checking. You are doing the basic reconciliation that variable, premium-heavy pay requires. The people who get consistent underpayment are usually the ones who never look.
