The managers use cell phones more than anyone, tho theoretically they are checking their work email constantly via their phones. Also, it allows them to be reached at all times (annoyingly also during meetings). Our director has a ring tone that sounds like bombs falling. Not sure who he uses that for but he tends to rush back to his office (pre-covid) when the bombs start falling.If I were an employer I would make it crystal clear, NO CELLPHONE USE, GET CAUGHT USING YOUR CELLPHONE AT WORK, YOU'RE FIRED.
Also two-factor security forces me to have to use my own cell phone to get codes to access some of our work systems. I kind of resent having to use my own cell phone when doing my work, and it does have a tendency to distract me into checking news headlines while I'm at it.
It was super annoying (pre-covid) to have people reading their phones during meetings, I wonder if people even realize their responsibilities, they show up without having read or thought about the substance being covered in the meeting, then they don't pay attention or engage. There are a lot of very passive people these days!
At the office there are signs on all the doors that cameras are not allowed (due to sensitive info), yet really we all have cameras because we have phones. Presumably they have watchers watching us covertly to make sure no one plays spy (in the office, I guess they are just out of luck during covid).
