I came across this early in my career in networking. I ended up having to support another technicians customer(we primarily managed our own workloads) and he did not use the tools(vault) we had to manage the network equipment credentials, so I always had to call him and ask him what the password is and why he doesn’t update it in the vault(it frequently changed) … After bothering him enough about it he said it was job security.

This was a 45k entry level job that he was years into. Why someone would want job security at the bottom part of the totem pole is beyond me, but that is where I mostly came across tribalistic tendencies(I worked in a lot of small/medium sized companies before getting a big break)

If I look up those people on LinkedIn, they’re exactly where they were or in another lateral position. They don’t tend to make it very far.

Wait why it it always line 12 though

As I understand, this is very low distance, basically for office settings. What ISPs will do to connect to/provide connectivity to a remote site is install point to point microwave radios. They are not impacted by weather too much, but they do lose signal strength if the radios are misaligned. There have been some funny situations where signals will be out of spec because protected birds like bald eagles are nesting on the radio and it is illegal to disturb their nests, or squirrels are storing acorns in them.

That is what service providers will do if they want to offer cellular connectivity to a small town where running fiber would cost millions of dollars. They will contract a service provider to provide CTBH (Cell Tower Backhaul) via point to point microwave radios. Multiple radios can be used for redundancy / to add bandwidth capabilities by bonding channels together, suddenly they can provide 4g/5g cellular connectivity without needing to spend millions of dollars in installing fiber.
