Ok, maybe no one is indispensible, especially when the downturn comes. What I mean is that if you monopolise a particular field within the company, you are considered a "much needed" person and you become the first name that comes to people's mind when they encounter problems in that field.
I must qualify that I do enjoy being the go-to guy in my department, but it is a double edge sword.
(1) Job Security.
(2) More visibility and thus better chance for promotion.
(3) More likely to get a better pay increment compared to the average peers.
(1) Over-reliance on you, and thus it starts to suck up my time, thus reducing productivity.
(2) Hard to go for long holidays, or even have to OT at home when on medical leave.
My boss once said that managers should train their subordinates to be almost as good as them, to the point that they can do the manager's things.
- When subordinates perform, it reflects nicely on the boss' management skills.
- When suboordinates perform to your level, you have the option of moving up to another level, since you now have a capable replacement.
A few months back, I have gotten a nice capable colleague, whom I have transferred my knowledge to. Now I can look forward to be absent without anything holding me back.
And it feels really good. ^_^
