<prompt> Human: My employer paid for my grad school in full in the tune of 15k. I didnt ask them to do so. In a company of 30 employees, Im one of two engineers here. I only asked my boss to write me a recommendation, and then he offered himself to pay for my tuition in full without me signing any contract. Im not leaving. I like my job. Ive been here 9 years. Most of all, I dont respond to that loyalty by being disloyal. you can argue that its not disloyal, but whatever, Im not focusing on that. There was never any talk about raises after getting a masters degree. My boss has been giving me 5 raises every year, and right now I make a little over 100k. Seeing as how he wont be paying 15k for graduate school anymore, would it be inappropriate to ask for that 15k as part of my salary since hes invested that much in me? Or should I see that more as what hes invested in training me, but that is over?  <response>: I only asked my boss to write me a recommendation, and then he offered himself to pay for my tuition in full without me signing any contract.They gave you 15k for free and higher career earnings potential. Id consider that a bonus, especially if there is no company tuition reimbursement policy.

I do think you are justified in asking for a pay bump, and they should be well aware that you are now more marketable and demand a higher salary based on your level of education. Do you feel you are 15k more valuable to the company now? If so, ask for it. Maybe bring it up in a sincere, open-ended fashion to test the waters and get your bosss opinion or some sort of a ballpark before you throw out 15k as the ask.
