That said, other than a handful of coworkers who I'm friends with outside of work, only my manager & HR have my personal number. This adds an extra step where the coworker should determine if getting in touch with me immediately is actually worth the effort.
So far, I've received one such phone call in 3 years. It was an actual emergency, and easily resolved by me at that time because they called me. If they had waited until the next working day, the issue would have blown up and taken much more effort for me to resolve.
This might alternatively be an argument for working with people who respect your time.
If I were to ever receive so many phone calls it becomes a problem I'll solve that problem. Right now I've had all of zero calls this year so I think I'll be right for the moment.
Furthermore, I don't find it particularly bright to host sensitive data by such a vague company. Bonus negative points for the infosec community using such.
Yes, a thousand times. People often write on company instant messaging just to ask things that can figure on their own.
People don't phone you for stuff that could have easily waited till tomorrow morning.
