Things to Remember to take with you Legally when you Resign
Any of your personal belongings can be taken when you leave your job. For people who have been at the same job for many years, this can be a lot of stuff. Some have a whole wall of pictures and several plants. It's best (and easiest) to clear your personal stuff out gradually over the weeks before you leave.
If you have any training materials that you think will be useful to you in the future, you can take them with you. They are of no value to the person taking your job unless they take the class as well, in which case they will get their own materials. If you have any certificates of completion for classes or trainings, those are yours and may be helpful in getting another job. Take any contact information for people in the company you may want to stay in touch with. We had a continually updated "white" pages that had the names, phone numbers, emails, and other information about everyone in the department. Because it was updated frequently, I just took one of the older ones with me.
Be sure to clean up your computer as thoroughly as possible. Remove Internet sites that you may have used for personal reasons. Delete old emails. Delete any files or folders that are not relevant to your job. Clean out your computer as thoroughly as you clean out your desk.
If you do not have copies of your reviews, you can probably get them from your boss or from Human Resources. Copies of reviews should be given to you at the time you have the review and you should always keep them. If you won any awards or were even nominated for an award, keep whatever evidence you have for that fact. These things are meaningful to any potential new employer.
Don't forget your personal calendar and your personal cup in the kitchen.
