Company will squeeze everything out of the talented one with no reward unless you know how to play the game or is sponsored. In one of my previous role, I did both my job plus my bosses’ job plus some more. Worked 10 to 12 hours per day for 2 years. So he got the promotion because of all that I accomplished. I was shipped off to a new assignment with no pay increase and an NI for not networking enough. My advise is to draw your boundaries.
I apologize for pulling someone's post - @2ryu+1ieOBRMm into a new thread, but I find this very interesting. Almost everyone here knows that they need to draw boundaries or they will be completely drained and burned out, but it seems that most people find it very difficult to do this in practice. I wonder why.
