Follow-up question to: Resignation letter: general tips and what to do if boss is not on site? and Put in my two weeks or wait?. [I would suggest reading these to understand the background.]
Yes, I was patient and waited for the paperwork for the new job and put in my two weeks to my supervisor. However, my boss (the president of the company) is responsible for mainly talking to me, rather than my supervisor (closer in rank to me, for a lack of a better word). After he arrived from his vacation, he approached me about how unhappy he was that I was leaving and how the company I currently worked for made an investment into me, and for me to leave so soon (2 months), it made him unhappy.
The "investment" of which he spoke consists of study materials and hours that the company funds for professional examinations that I take as part of the profession I am in. Neither the official policy nor my offer letter state that I have to repay him anything.
Immediately after he started stating that he was unhappy, I immediately offered to write him a check. He did not want the check, and stated that in order to end on "good terms," he was suggesting that I do a project for him most likely starting a few months after my employment is terminated. For various reasons, I verbally agreed but I requested that he send a contract to me.
Looking back at this, I regret my verbal agreement. I do not intend on signing whatever contract he has for me. I plan on going back and stating to him somehow that I do not owe him anything and that I will not agree to this future project done after my termination.
How do I approach stating such in a professional manner?
Side note: I still have a week left of work until termination, due to my two-weeks' notice. This is in the U.S..
