I’m an ex UK employee and started with Reuters this Reuters package.
It’s was 6 weeks per year (11 years * 6 = 66 weeks salary).
I was aged 50 so got 6 months notice period that is purchased as a lump sum from you.
2k towards training costs (regardless if you use it or not).
Bonus paid based at 10% aka 1/2 of bonus if you were April plus 6 months being layed off.
First 30k in uk is tax free.
You can also get redundancy paid tax free into an AVC (£40k limit , but you can use unused allowance from previous 3 years aka 120k more).
I wanted redundancy and volunteered at time.
