You've done it. You have found a new position. You've written a nice letter of resignation stating you would be leaving in two weeks to pursue employment elsewhere. Although you are quitting, now is not the time to quit working. Employers remember the final two weeks of an employees time on the job more than the entire rest of the interim of employment.
Several reasons come to mind.
First, it gives the employer a head start on filling the position and avoiding loss in productivity. Second, it allows the employee who is leaving to finish up current projects and to lend training to a new hire. And finally, it allows for a smooth period of transition for all other employees who would be affected by the change in personnel. The final two weeks on the job are just as important as the first two weeks. It is important for a leaving employee to work diligently to complete tasks and provide good transitional assistance to the incoming employee or to the other workers who will be taking on the tasks of the position until a new employee can be hired.
