I am taking a break from being a senior sysadmin because I got burnt out for the third time and am happily pursuing a data science degree. I've been the contractor and the employee. My two cents is that companies have become so focused on killing upward mobility on purpose as a cost saving measure due to what I feel is increasingly more short term thinking. I can't tell you how many times during my contracting days I heard a story about how $company used to have one or more full time employees who setup, managed, and knew all their systems, but they decided they would rather save the salaries and just use the contractor "when needed". Of course half the time it was some halfassed MSP type shop that didn't know their ass from their elbow, didn't really care about being proactive, and milked billing enough the companies ended up spending just as much money as the salaries but with 1/8 the effectiveness. Throw in outsourcing to foreign countries (Goldman Sachs) and abuse of H1Bs and yeah, I'd say the rise of contract workers is killing upward mobility. That said, its not the contractors fault, its managements. My view is this is largely because the CTO and CIO positions are failing to properly brief the Cs/board of directors on why they shouldn't be doing this, and that is largely because the CTO/CIO is too much a management and not enough tech. Often I would even see companies without a CTO/CIO, and some poor greybeard would be haphazardly trying to run an IT department and speak board speak at the same time, in the end doing neither well because they had little backing from higher up. This is why so many companies are literally drowning in their own technical debt due to greediness and short term thinking! I think its time for more technical people to go get an MBA and shake up the stagnant CTO/CIO positions. For a long time I just wanted to be in a cold data center all day with my head in a terminal doing good work. As a senior sysadmin though I have learned that I should have been playing the politics game in the meeting room to protect my department and the company. I wish I had learned this sooner.
