If your company started using computer monitoring software which created a report on all of your computer and phone activity at the end of every day and emailed it to you and your direct supervisor as a productivity tool...would you have to change some things quickly? Would you be in trouble if they started doing it and didn't TELL you they've been doing it for a month already?
Would you accept a job offer with a company who told you, during the interview process, that this was standard procedure?
