For a lesson in how not to get out of paying redundancy pay, click here.

The lesson from this case is if you want to avoid making a payment on termination of employment by reason of redundancy, get employees to agree to short notice in return for not being required to work their notice and make it clear to them that any payment you make is appropriated (stated to be paid in satisfaction of) redundancy pay as it is possible for employees to waive their right to notice pay, but not their right to redundancy pay. The right to receive redundancy pay can only be waived with a Compromise Agreement (or COT3).
