Find the overlap between a shift and a chosen night window. Compare additive premiums with multipliers and see why the position of an unpaid break matters.

Pay and payslips
Check your paycheck
Compare dates, paid hours, rates and extras before reviewing deductions. Use a seven-part reconciliation and a fictional example to locate a pay difference.

Understand the difference between earnings before deductions and take-home pay. See a gross shift example and why reimbursements and deductions need separate checks.

Distinguish every-two-weeks pay from twice-monthly pay. Follow a two-week gross example and check overtime weeks, cut-offs and illustrative payment dates.

Build a planning range from previous take-home payments, distinguish gross estimates from available cash, and account for pay dates and variable work costs.

Understand rotating shifts
Map repeating work and rest days onto real dates. Compare 2-on/2-off and 4-on/4-off examples, handle swaps, and keep the planned rota separate from worked time.

Keep planned and actual shifts distinct, record breaks and changes promptly, and review a changing week with a practical recordkeeping checklist.

How loan amortization works
Read a fixed-rate loan schedule and separate principal from interest. Follow the first payments, final-payment rounding and the effect of extra principal.
