True. Sorry should have specified in the US they can just say we are letting you go and you’re done. Which as far as I’m concerned is basically a catch all statement of “we aren’t going to tell you why, we are just firing you”.
You can’t do that in the US. They can make up a excuse but they can’t fire someone for no reason
I worked for a company that trained me that “right to work” meant I could fire someone and tell them it was because I didn’t like the color of their shoes. I suppose that’s an excuse or reason but at that point is there really any difference?
