I retired as a senior engineer from a HUGE world wide company.
Before I retired, one of the vice presidents and my immediate manager were in my office when the VP’s cell phone rang...he looked and said he didn’t need to take the call...I told him I didn’t own a cell phone...
He looked at me funny and asked why??
I pointed at my boss and then at him and said, “So him and you can’t call me...”
He thought for a second and then said, “You are the smartest man I know...”
I am surprised they allowed you to do that. Every job I have held since 1998 required that I had a cell phone, and be available 24 hours a day. It was a condition of employment.
"And by the way, you're fired!"
I don’t own one either, back in the day they tried to make me carry a pager. I just left in the office desk draw every night when I went home for work.
