Common mistakes include assuming verbal promises are legally binding, failing to read the employment contract, and not checking payslips, holiday records or working hours. Some people also delay raising concerns, miss employment tribunal time limits, or resign before taking advice, which can affect their options. Keep copies of relevant emails, contracts and payslips, and follow your employer’s grievance procedure where appropriate. Rights can depend on your employment status, length of service and the specific circumstances, so consider speaking to a solicitor regulated by the SRA or contacting Acas for guidance.
