The rule of thumb is that you do not give your resignation from your current job until you have your new job offer in hand. Otherwise, you may quit one job only to discover that you don’t have another one to go to, or that the terms of employment in your letter of offer were not quite what you expected.
You should write a letter of resignation. In practical terms, this letter should be short. It can be handwritten or typed. You do not have to mention the reasons that you are leaving the job or problems that you encountered; sometimes, these things are best left unsaid in the resignation, but you may wish to bring them up in a last meeting with your boss (sometimes referred to as an exit interview).
The key ingredients for a letter of resignation are:
- The length of notice.
- The last day of work.
