By signing a settlement agreement, an employee agrees to certain terms, such as waiving their right to bring claims against the employer. However, not all claims can be settled under a settlement agreement. Claims in respect of accrued pension rights and personal injury claims that have not yet arisen, or that the employee could not reasonably be aware of, cannot be settled. Claims in respect of certain statutory rights also cannot be settled, in particular claims for failure to inform and consult with appropriate representatives on collective redundancies or on the transfer of an undertaking (TUPE), as well as claims for statutory maternity, paternity, adoption or shared parental pay.
