Please accept this letter as my official resignation from my position as volunteer and part of the Company Name team. With my family’s recent financial crisis, I have been forced to take a full-time job, which effectively removes any free time that I had for the cause.
I want to take this time to thank you for all of your support for giving me the opportunity to help others. I would encourage you to call me if you need help during a holiday or weekend event as I may be able to make time to help you out. But I will no longer be able to give 20 to 25 hours per week to the organization, as I have been doing for the past several years.
I enjoyed my time with Company Name and will cherish the friends I have made and the memories I have acquired. If you do need to contact me for any reason, please feel free to call me at 000-000-0000 or email me at firstname.lastname@example.org. I will always be available to Company Name whenever I have time.
