We have all had bad days in the office or had an awful boss. Those things make you not enjoy coming into the office. But if you're extremely unlucky your employer does something to you that irks you to your bone making you want to quit right away. Take a read and be thankful your employer isn't like these.
"I got another job offer for a position that paid about 50% more than what I was currently making. My supervisor made a counteroffer that more than matched it - I just had to jump through some paperwork formalities. That paperwork gets dragged out for about 2 months, when I'm told that the supervisor didn't have the authority to make that kind of counteroffer. Instead I was told 10%, take it or leave it. I had the offer in writing but it wasn't an official document - fighting it would have been a long uphill battle. I took the 10%, found another job, and left without helping train a replacement with no f--ks given. New job was even higher than the original offer, so it all worked out" (Source).
