The legal starting point
Gross pay is before deductions; net pay reflects contributions, withholding and other payroll items. There is no universal conversion percentage. Status, working arrangements, family circumstances, benefits and reductions affect the result. Withholding is a tax advance, not necessarily the final liability.
Documents to gather
The contract and amendments, payslips, starting date, working arrangements and received notices. Keep evidence of receipt.
Your next step
Write a short timeline and state the outcome you seek. Request a written explanation if an amount or decision seems wrong. Before signing, acknowledging a debt or allowing a deadline to pass, check the consequences for your circumstances. An amicable step does not automatically suspend a statutory deadline.
