how to find a good reason for resigning

You are going to need a reference from them so you are right not to give the reason. I suggest that you find another job before you quit this one. Then you can give the reason that you are resigning in order to gain a better position. Don't forget to thank them for the "experience" of working for the company and be polite to your boss in case of the future. Of course, some healthy problems are also useful reasons for resigning. Good luck!

"good reason" it should the real reason why do you want to resign. be true to your self and say it straight to your boss and be firmed to your decision.

It is difficult to find a reason for resigning. If you don't want to go back to the job again and don't want to face the compelltion of your manger or team lead to take back resignation, the best way is to tell them that you got job in another company and you have already made up your mind to join there. Another reason is sickness, you can tell them that you are affected with a serious illness and want to stop working for sometime to take treatment.

Say it straight. Tell yout boss straight. You don't really need a good reason to resign. I think if you tell the truth it will be alright. Maybe if your lucky your boss will offer you a massive pay rise to stay, you might stay for the cash but still hate the job. The choice is up to you. Personally I would tell your boss straight up.

moving for a better compensation job always make a good reason. and its the best reason i know so far. as most of my colleagues uses that reason. but if your boss really wanted you, he/she or your company will have a counter-offer. if it fits your need, then grab it and stays. one thing i learned also is that when you decided to resign, make sure that your department have extra manpower who will handle your job. this is usually the reason why your boss doesn't want you to leave.
