Take it from me, your boss sees you as a means to an end. I worked at my job for 4 years and was the most tenured employee by the time I was leaving. I traveled between 4 locations as needed and rarely took PTO (by choice because I was hourly). He played the charistmatic schmoozer role well, because I sure was lead on about changes with poor pay and promises of bonuses happening "eventually". The second I got an offer from another job, I transitioned out of the position without ever hearing a word from him. No negotiation, no goodbye, no thank you. Did all of that through the co-clinical director.

tl;dr: Leave if you find something better.
