Give 2 weeks (or more) notice
It is never ideal to give less than a two week notice when leaving your job. Make sure when you accept a new position, you offer at least 14 days before your start date. Not only will your current employer appreciate the notice, but your new company will be able to see your professionalism and character before you even begin the new job. When possible, offer more than the expected two weeks. If you don’t have a hard deadline for starting your new gig, offer to stay with your current team until a replacement can be found.
Tell your boss first
It can be exciting when you’re offered a new position, and you can’t wait to tell…EVERYONE, but you need to hold it in and tell your boss first. Respect his position of having to find your replacement and don’t make him come to you for confirmation after hearing the water cooler rumors that you’re moving on.
Be honest in your departure
When you explain your departure to your boss (before anyone else), be honest. No, you’re under no legal obligation to explain why you’re leaving or where you’re going, but you’ll find that being straight forward now, will leave the door open if ever there’s an opportunity for you to return to the company. As a side note, when you start sharing the news with your co-workers, keep the story consistent. Don’t give your manager one reason for leaving and then dish out different stories to fellow employees.
Work until your final day
Don’t mistake your two week notice for two week staycation at the office. Although you may be moving on, everyone else in the office is still focused on moving the company forward, and they shouldn’t have to pick up your slack because “you’re leaving anyway.” Work hard, complete projects and if possible, train your replacement so they feel confident in the position when it’s time for you leave.
Follow-up after the good-bye
I recommend sending a thank you note to management. Acknowledge the things you’ve learned and will carry with you into your new position. Thank your boss for her time in training you and having confidence in you to fill the role. You may even mention that you’re open to helping your replacement in any way possible in the near future. Keeping your contacts after leaving a job is not only important when it comes to strong references in the future, but you’ll also be glad for the strong ties if ever you hope to rejoin the company.
