Agreed on the work front - this has been the case for some time, and the law supports it.
I'm also not sure I agree with this part:
Taylor says he has seen cases where peers and colleagues are recording one another.
"That cannot be deemed a healthy culture — it just can't be, by anyone's standard," he says.
It's hard to cultivate trust, he says, when every word you say might later be used against you.
Unsurprising for someone whose interests are on the employer's side. But I would say it's the opposite: people are tired of those in power being taken at their word when they don't deserve to be, and this is the inevitable result. You can't have it both ways, and openness is definitely not a one-way street, as much as employers would like it to be.
I'm far from a fan from the "if you're innocent you have nothing to hide" argument, but in a social context the lines aren't in the same place IMO. I don't necessarily think someone deserves national shaming because they had a bad day and were mean to someone, but by the same token I'm generally in favor of anything makes someone in a position of authority (police included) tread more carefully. Perhaps the answer to "who watches the watchers" should be "everybody."
