Is this like mandatory you have to work, or ... you have to work or you'll be fired?

If the former, I always wonder about folks who were set to retire, age out, got a new job they're starting, have health issues, etc..

Have to work but can phone in sick, more and more of them will phone in sick.

It's a weird system over the pond I have to say.

I think its also, you'll never have a federal job again.
