re: Why do you have(traditionally) to give a two weeks notice, but your company can

If the employer treated you like shite, frick him he doesn't deserve your etiquette.

But if your employer treated you well, and paid you fairly then you need to give him two weeks.

I had a boss that treated everybody like shite. Worked for him for a few months and finally had it with him. Walked into his office one day and told him I quit. He said ok you got two weeks. I said no, sorry. I can't stay here anymore.
