@90aca61c I think there should be some reciprocity.

If you require two weeks notice before I quit, you should give me two weeks notice before you lay me off.

If you wait until Friday at quitting time to tell me that I have to work all weekend, I should be able to tell you Friday at quitting time that I'm not able to work the weekend.

Most of that type behavior is poor planning on management's part and they want superhuman behavior from you but shitty leadership from them.
