I have same situation with you, maybe worst....i also going to resign after working for 3 months, but the situation is when last time my boss interview me, he mentioned that he want to hire someone who will work together with the company for years because it's time consuming to hire and train another new ppl, somemore all their project are very urgent, if the employee simply left, it will burden other ppl's work. So, that time he want me to promise him i will work at least one year at this company (although without black and white)......Therefore, i promised him.....
But now, i get a better job and better offer, i hope to leave..........
What can i do now? will my boss very angry if i resign ?
should i tell him directly i get a new offer?
pls advice.....
