Eh, not necessarily. Higher skill jobs tend to be harder to replace, especially if you're really good at something specific to the company you work for.

It's hard to get there any maybe not worth it (my comment was a bit tongue in cheek, like "don't be unattractive").

Surely you're hard to replace since you do a great job in your role.

I'm in a similar boat, my team can do just fine without me and I make sure they can do well without any of them, but I would be hard pressed to replace most of them because they're really good at what they do. Nobody works extra hours, and people go home early if they're not feeling productive, and the work gets done on time almost every time.

I think I'm hard to replace for similar reasons. We've gone through 2 others in a similar position as my own and went over a year looking for one before we found the third. I'm not worried about my position going away since my boss seems to like our work ethic.
