I have a friend who started a new job about three weeks ago and they hate it, lol. They were essentially promised the world and had nothing delivered, so it's fair to say the job hasn't met any expectations. They are yet to be paid because of a stuff up in HR, and there was no apology issued about that either, it was simply a case of suck it up.
Safe to say they are already looking around for another job. My own resignation record is about 6 weeks, and I knew that I wasn't going to be able to deal with the narcissistic person in charge there, so I simply walked out and told them I wasn't going to be returning. I don't think it's a pattern for me as I've lasted in other jobs for years

So is 3 weeks of not being happy long enough to think about resignation, or should they give it some more time? I'd love to hear stories of jobs where you knew it wasn't going to work out!
