Most people leave an employment situation because they are unhappy with something, and sometimes an individual is tempted to leave right away. But here are three reasons why it’s important to give a two weeks’ notice:
(1) It’s customary
(2) It’s important to leave your current employer on good terms
(3) In the eyes of your new employer, leaving immediately may reflect poorly on your character.
Don’t leave hastily; you may regret it later.
