Yes, it is generally acceptable to resign without providing specific reasons. Many employees choose to resign for personal or professional reasons that they may not wish to disclose. Here are a few points to consider:
Many people leave their jobs when they're faced with personal reasons like health issues or family emergencies. You don't need to disclose personal or family matters. Sometimes, saying, “I had to leave for personal and family reasons,” is enough as long as you explain why you're ready to reenter the workforce.
You are under no obligation to provide a reason why you are leaving, just as you are not legally required to provide notice at all.
You don't have to give a reason for your resignation.
Can my resignation be “with immediate effect”? Is it a good idea to do so? If you have less than 1 months' service, and no notice provisions in your contract of employment, then you can resign with immediate effect. You otherwise need to give 1 week's statutory notice (or longer if your contract provides for this).
Dear Manager's Name, Please accept this letter as my official resignation from my position as Job Title at Company Name, effective Date of Resignation. It is with a heavy heart that I submit this resignation letter due to personal reasons that require my attention.
Keep your letter concise and to the point by summarizing your reason for leaving in one sentence. If the situation is complex or you have multiple reasons for leaving, focus on the primary cause. This statement is most impactful when it's brief and direct.
State your resignation intent and the exact date that you'll be leaving. If you're comfortable, give a broad reason on why you're resigning. Show appreciation and gratitude for the work experience. Express your willingness to assist with the transition.
I wanted to let you know that I've decided to resign from my position at XYZ Company, effective (date). I want to express my gratitude for the opportunities and experiences I've had here, and for the support and guidance you've provided me during my time at the company.
You don't need to explain why you're leaving in your resignation letter. But, choosing to do so allows you to give context and provide feedback, which can help you maintain a positive relationship.
