I think having constant surveillance can have a negative impact on work life. I know that when discussions moved to Slack at my work place there was a very different way to communicate due to us knowing our conversations may be read. Not that there were any instances of harassment, but sometimes it can be relieving to tell a coworker that your boss is a dick. It can help get feelings out before they build up. I do see some value in surveillance, such as the GP's instance (whether or not it's true -- it's a reasonably plausible story). I, however, don't think that constant surveillance that upper management has free reign over is good. I did have an idea about this. Is there a way to have a file (such as video/audio) encrypted in such a way that it can only be decrypted with multiple keys? In GP's case, GP and the employee that made the accusation? That way you can still feel safe(-ish) that your small slacking off won't risk your job, while allowing for evidence in serious situations such as GP's.
