Craig Fisher, who writes at FishDogs - Career Branding for Social Animals directed me to the following article:
The generalists' range of knowledge makes them a better candidate for promotion to a supervisory or managerial position. When that happens, the generalist may not understand that in addition to the high stress of being expected to know everything technical, they will now be subjected to the stress of being involved in corporate politics. Whereas they became a "Jack of all trades" because of their love of science and technology, now they need to become an expert at "covering their ass", "back stabbing", and other political games.
If an individual, who became a "jack of all trades" because of their love of science and technology, refuses to accept a promotion to a supervisory or managerial position, they will be considered to be "lacking in ambition" and will not be receiving any future meaningful salary increases.
Should You be a "Jack of all Trades" or a Specialist? by Stephen Bucaro
I'm good at what I do, but like the article mentions "master of none" and I think that's becoming quite the liability. All the jobs I want to apply for I just don't have quite the depth of experience needed. It's very frustrating to know that given half a chance I could become masterful in the time alloted, unfortunately, any particular skillset is needed now, not in a few months. I guess I don't mind meetings and telling people what to do, but I already know from experience that I don't do well in office politics. I just want to get things done.
So, what's a girl to do? I still have mouths to feed and bills to pay.
3/2 Update (also in comments)
Contract extended :). I don't know my new end date, but being here past the end of this week is good news.
