I've been working a stressful, understaffed job at a certain popular shoe company that starts with an S, for about five months now, and I cant do it anymore. My manager is the worst part, but I have to get through her to quit, can I just leave her a letter on her desk or something and get the heck outta there or do I have to fess up and try to not panic saying it in person? Will quitting without notice affect getting my final paycheck?
