I work in IT. I am 50 and mid level in a department of 8. Pay is fair, hours are long. Ahead of me are three others that are the most negative people ever. They are entrenched and will never advance or leave. My chances to move above them are slim no matter what because of seniority rules. Question: I have an opportunity to self study into another skill set that is kinda related. Probably won't be used more than a couple times a year. No chance to turn this into more $ or benefits. I am thinking “what's the point?” Thoughts?
