THE PROPER WAY TO RESIGN
Resigning from your old job and starting a new one is always a difficult, multi-layered process - especially when you have to coordinate the two timelines. The general rule of thumb is to give your current employer two weeks' notice before leaving. But beyond that, it's important to make sure the date you resign coincides with your start date at the new company.
Try to avoid an extended start date. Even if your new job begins in 10 weeks, don’t give 10 weeks’ notice- wait eight weeks and then give two weeks’ notice instead. By doing this, you will safeguard yourself from any potential problems that might arise if your new company announces a hiring freeze shortly before you are set to begin working there. If you give your old job two weeks' notice after announcing your resignation, then you won't have to deal with the envy or scorn from others that may come as a result of your new role as a 'lame duck' employee.
Some businesses will handle your exit plans for you. I know a candidate who was escorted off the premises by a security guard the minute he stated his desire to work for a direct competitor. He was, fortunately, compensated for two weeks.
You should submit your resignation by hand, if possible on a Friday afternoon. If you can speak with your immediate supervisor in his office, do so. When you intend to leave your position, you should give your supervisor a letter stating the date on which you will leave. Make it clear to him that you're grateful for the opportunity to have worked with him, but an irresistible chance came up, and you had to take it. Assure him your decision to leave wasn't made lightly and doesn't come from a place of resentment toward the company or anyone there.
It is important to be firm in your decision and explain that you would prefer not to receive a counteroffer. This way, if you are offered more money, it will not appear as though you are rejecting the offer personally. Be sure to express your gratitude to your boss for all the opportunities they have given you at the company, and let them know that you will do everything you can to make leaving the business as seamless as possible. Finally, inquire if there's anything you can do during the next two weeks to assist your successor, tidy up loose ends, or delegate responsibilities.
There's no need for your resignation letter to be long-winded – simply state that you are resigning, the date of your last day, and thank your employer for their time. If there are concerns that are important to your former employer, he'll hold an exit interview for you, at which point you may discuss them ad infinitum. Make sure to have an extra copy of your resignation letter for the company files. That way, there will be a written record of the situation surrounding your resignation.
