I’ve reached a certain level in my current role where I’m being regularly called upon to attend outside events as a representative of my company. At first I was happy to, but now I’m being asked to go to more and more functions and it’s eating up a considerable chunk of my spare time. I’m beginning to think my company is taking advantage of me, but at the same time I’m admittedly building up a better network. Should I just go with it or is there a point where I should draw a line?
