Turning in your resignation from your current job
Unless you really hate your job and/or your boss, resigning from a job will be uncomfortable. You’ve spent a significant amount of your life with your fellow employees, and you probably consider many of them friends. If your supervisor doesn’t know you are looking for a new position he/she will be surprised when you give your notice. He/she might express some sadness, disappointment or even hostility towards your decision.
When you turn in your resignation keep in mind why you are doing so – it’s to take an opportunity with a new company that’s better (for whatever reason) than the one you have right now. It’s going to be uncomfortable for a few minutes while you give your notice, but you’re taking a step that is better for you in the long run.
Don’t feel guilty when you give your notice. The company wasn’t doing you a special favor by giving you a job. You worked for them and they compensated you for it. It was a business relationship, not a personal one. You’re not doing anything that could be considered a personal attack. Don’t let yourself feel that way, and don’t let your current supervisor make you feel guilty for leaving.
You’ve determined the new position is a better one for you, whether it’s because of the company, salary or career path. The few minutes you feel uncomfortable while giving your notice will quickly be forgotten when you start this excellent new opportunity.
