I mean as IT nerds we like to moan about being the only ones who can fix certain things, but in most cases it’s where our job security has come from.
It may not be intentional on our part, but it’s not such a bad place to be all things considered.
As much as I work to fixing key man dependencies to some degree they are part and parcel of the work.
Yeah mine wasn't intentional at all, in 2019 we lost the senior guy and the guy just under me in the same month. Of course 2020 occurred so we had no new hires directly after that, so I ran the systems with an intern from late 2019 to 2021, was stressful to say the least.
We managed to hire two guys in 2021 and it got easier as we were doing an upgrade in that year and the intern had really pulled up his socks and got himself going, in 2022 we hired another guy so we were like yeah finally team back to normal size.
2023 one of the guys from 2021 resigns and leaves, fine we've stabilised the systems and we can handle it, 2024 the guy from 2022 resigns like okay we're down a bit but we're still fine.
Ex intern is promoted to senior position in 2024, but salary disputes means he resigns in early 2025, then the first guy from 2021 has a major car accident and is having some memory issues.
So literally from 2019 I've kept the systems running, upgraded and monitored, especially since I needed to ensure new guys could get up and running quickly and that my weekends don't get disturbed too much.
So sadly I became the only one who can handle the current systems, but the new guys want to migrate to their system, but having done a migration in 2016 it can take 3 years to do that especially if you want BAU, so will see.
