Oh, I'm definitely not getting fired because, well, I'm the only guy holding our webapps in one piece. If I left, most everything would go to hell. I do tons of good work for them. I think originally I was invited but then she decided not to keep me in the loop because we have a problem keeping people in the loop. We want people in the loop! But keep them out!
That's so full of shit. I see essential people getting fired all the time. I don't mean people who just think they're essential -- I mean really, actually damagingly essential and when they leave things break that week and stay broken for months or the project flat out dies or it gets outsourced to a series of bad outside firms who never make it anything like it was.
And generally those people who might as well be locked in a room by themselves -- whether by their own choice or because it appears to be necessary to get anything done -- have brain damaged, twisted software which needs to fail and be completely rewritten to match maintainability and end-user requirements. So a lot of those essential people who are fired, even though it breaks stuff, are sometimes fired for good reasons and get good outcomes in the long run.
Even with all that -- don't kid yourself. When the fuck did Management make decisions which were good for your projects, over what they wanted to do? How reality based are you requiring mgmt to be? Are they giving you 20% raises every year? If not, then don't think they're even starting out with that special untouchably employed opinion of you. If they do think of that way, you're still getting fired if they feel like it.
