Most of the people I know have learned to text me if they want a response. Close family member I might answer a call from, but work calls get ignored. I already know what the call is about 99% of the time, and I also know that it will rarely require more than one,maybe 2 words from me to answer the questions being asked. They'll want to know if I'm done a job, or if I can go out on a job. I'll say yea or no, and that's it. If the boss calls, I know he's gonna prattle on about something for a few minutes at least because people seem to feel like they need to make the phone call seem worthwhile. I don't wanna talk nonsense with anyone for a few minutes, so I ignore the call, he texts, I answer, everyone is happy.
