Most of the employees that were in the US did not have contracts, so most of them could be let go at any given time. However, I recall that when he tried to fire a bunch of workers in Ireland, they just lawyered up, and their lawyers solved the issue.

In places where contracts are standard practice for employment, it’s a fairly common that when a company wants you out, they pay you a large amount of money or the remainder of the contract to leave and not return.
