As my employer, I wish to formally bid goodbye to the company by writing this letter to you. I have been an employee of your company for fifteen years and it is quite sad to be leaving your company for personal reasons.
Working for your company has taught me a lot about the intricacies of a career in sales. I was given various opportunities for career growth and I have also had the privilege of attending trainings to improve my skills and knowledge in the area of sales. The company truly takes care of its employees and I am honored to have been part of the company.
I sincerely hope that the company continues to reap more success this year and the years to come. Your excellent service deserves such glory.
