Dear Mr. Smith —

This is my notice to resign from my position as Product Designer from Company Inc effective October 1st, 2020. I am providing no notice of my resignation and no transition period to my resignation as I have experienced frequent harassment from a coworker in the workplace. While I have not yet spoken with an attorney that practices state employment law, I plan on doing so.

The harassment has come in the form of constant sexual comments and uncomfortable mentions of my physical appearance. The initial claims were made to Human Resources, and attempts were made to handle the situation but have failed. I’m unable to produce results with this working condition. And I would constitute this a hostile environment that I must depart from.

Please consider this my formal resignation letter and notice, effective immediately.

Dear [Recipients Name],

It is with deep regret that I am submitting to you my resignation from my duties as the assistant project manager of the marketing division.

As you may know, there has been quite a lot of fights between one of my colleagues who is also an assistant manager such as myself and me. As we have the same duties to fulfill, we have found ourselves to be constantly butting heads with one another which has resulted in quite a few times to a project turning out to be not the best it could be. I believe that it is a clash of our beliefs that has caused this problem for our supervisor and us as well. I would like to take the initiative and resign to facilitate a better working environment for everyone involved. I have also just gotten an offer to resume my studies, and I am seriously considering that idea as well. I feel that now is the best time to push through with this resignation that I have been thinking of for quite some time now.

Please know that I have been happy with my stay here at Red Industries, and I have greatly appreciated everything I have learned here. As a repayment of sorts, I would like to help out in training my replacement so that the transition would be easier.

“Dear Mr. Coursey,

I am sending this letter to inform you of my immediate resignation from my position as project manager at ABC Company. Unfortunately, this resignation is due to toxic coworkers who have been harassing me since the recent promotion I received. The rest of the employees have behaved increasingly hostile to me since I was promoted over them and I can no longer keep coming into the office under these conditions. I will not be coming back into work so please accept this letter as my official notice of resignation from ABC Company.

I apologize for any inconvenience that my resignation may cause to ABC Company. It is my hope that by bringing this situation to your attention, some type of action can be taken to prevent this from happening to the next person who steps into my position. If you would like to discuss this with me further, please contact me at (555)-555-5555 or [email]

Although I am very upset at the situation that has necessitated my resignation, I am glad for the business experience I have earned by working at ABC Company up until now and know that it will serve me well in my next job. Thank you for your understanding and cooperation in this matter.

Yours sincerely,

Sophie Vanderbilt”

“Dear Ms. Cordoba,

Please accept this notice of my resignation from the position of sales representative at SalidaCorp. My last day with the company will be September 4th, 2019, in order to give our team time to transition.

While I am grateful for the opportunity to work with the SalidaCorp sales team, I have come to the conclusion that I do not share the same work style and long-term goals as other members of the team. I now think that it will be beneficial for me to find a position that better suits my methods and pace. I would like to thank you and the team for training me and for helping me through my first couple of months. Please do not hesitate to reach out to me if there is anything that I can do to make the transition period less challenging for you all. Thank you again.
