It is with the most profound and sincere regret that I must announce my resignation from (insert company) effective (insert date).
(insert company) consistently provided me a professional atmosphere and treated me with the utmost respect. There were many opportunities to expand my career and take on more responsibility. I’m genuinely grateful for every day of these (insert duration).
It hurts my heart, but business dictates decisions outside of emotion. For me, this is the best path. Our incentives do not seem to be in the same direction, which is both respectable and understandable.
I hope there will come a day when (insert company) can afford me another opportunity. I’ll wait for that day; however, until then, please accept this letter of resignation as a formal sign of my esteem for this great company.
