My role used to be more a sitting-down type and I could focus on my work. But as I advance to a relatively senior level, I begin to be regularly called upon to attend external events as a representative of my company. At first, I was happy to do so as an occasional change of mode of work, but as time goes, I’m being asked to go to more and more functions and it is eating a considerable chunk of my spare time. I’m beginning to think that my company is taking advantage of me, but at the same time, I am admittedly building up a more extensive network. Should I just go along with it or is there a point that I should draw a line?
