Learning the curves of leaving a job and getting a new one is a must most especially for those people who really have not spent so much time with one job.  The complications of moving to a new job webs drastically that at times (when the decision is not carefully thought of), it is too late to resent the action.

One of the few things that you must do when you are moving to a new job is to determine whether the company is giving relocation package should you decide to move out.  Some of the more inclusions in the package would be professional movers, who will help you out with moving your things; a new apartment or condo unit where you will be staying, and how far the deposit and advance would go and other moving costs.  

If they are indeed relocating you with the package, learn to ask from your company the location where you will be relocated.  At times, the relocation place is too far from the workplace. This is a blatant killing of your time.

As for the must-not-do, it is advised that you do not go over relocating and moving to new job in just a snap of a finger.  Remember that new job on a new place requires more time to think about it.
