I have been temping for the past few months and was just recently hired on full time. I have been kicking around the idea of quitting, but now that I have been hired on full time I feel like it would leave a sour taste in their mouth if I were to quit so soon. If I'm not mistaken, employers have to pay the temp agency a fee to release the employee (a couple thousand dollars from what I've read elsewhere). Besides that, I was just informed I would have to take a training module within the next couple weeks that would cost the company a couple hundred dollars. I speculate they've pumped a fair amount of money into employing me and training me, so I almost feel obligated to stay with them.
Working conditions are tolerable for the most part, but a couple of things sit in the back of my mind and nag at me; too much down time, low wage, unsupportive boss, and a few other things.
Obviously I would try and find other employment first, but me quitting is inevitable. If not within the next couple weeks, definitely within the next few months.
