I've been recently made redundant due to our position moving to our overseas office in the Philippines. However, in order to get my redundancy payout, I had to sign a contract to basically say I wouldn't sue to the employer or take any legal action toward them. However, I need to take action to claim underpayment of wages and conditions. Is it actually legal under Employment Law for them to force me to sign a contact to receive a redundancy payout? One of the conditions were, we were paid on an hourly rate according to our contract, however, we worked 40-hour weeks, no overtime or time in lieu and I thought the maximum weekly normal hours was 38?
