I mean... I never meant that I was irreplaceable, but it would be a pain in the ass to in the short term to find someone to deal with this. They have become BIG on cutting overtime. They're already understaffed and barely making it staffing wise with me here. Without me they are screwed unless they can hire people for these accounts I've been filling asap. Which isn't going to happen. It's already to the point where if I call in sick, they eat over and double time for the entire shift. They just don't have the staffing.
This could be said in a lot of places though. I wouldn't confuse filling your shoes a pain in the ass with irreplaceable. The field I work in for example was adapoted by the local government sector in 2008. Went from a privately run buniess to locally government run. I've been there since its inception and built everything to make a once privately run business into a self sufficient local government council department. The changes in procedures and policies has been hard and long too. We've also acquired more to the program, more venues and built extensions on the existing centres. Myself and my direct boss have been there and moulded everyting to what it is today.
We have respect from the staff and basically are the heart and soul and everything that happens, doesn't happen without us. From an operation point, I've been that for years now. I have the upmost respect from the staff and long term staff that have been around for years appreciate and know the work we have put in. Now because the big boss is an egotistical credit taking prick, and I challenge him and call him out on his stupidity hates my guts and because we are more self sufficient today than ever, if I left tomorrow, while things would be very very difficult in the short term, there is simply no way it won't run. It may not be as efficient or well operated but nevertheless it HAS to run, it won't close down if I walked away.
I use to think I was irreplaceable and felt invincible. I've come to my own realisation that that was arrogant, irrational and egotistical thinking. It's been a great awakening and personal learning experience. I've had issues with my job and the lack of respect and even borderline mental struggles, this has partially been what I needed to figure out.
I think my point is learn from their response and fully think and accept it. Stads is right, think about from their point of view, and are they going to think the same as you? Looks like no. I never did this but when things were mentally getting tough I stepped back and had to look from others perspective to try and realise what was going on. No fucking way would my boss think I'm replaceable. He knows it's so much easier to have me and have me do everything, but he'll never admit it or beg me to stay if I decided to leave, no way.
If you move on and with your other post, definitely sit down with them and lay it all out. They probably won't give a fuck, but it will be good for you to move on. Good luck mate.
