The whole atmosphere here has been somewhat different since they put that spyware crap on the library assistants' computer without my knowledge. I found out about it from them and luckily it didn't land anyone into too much trouble before I got rid. This crap has to stop. As far as I know it has but I've been shunned at some levels for protesting about it in the first place. Just my opinion, but if you have a problem with an employee there are many other ways to go about handling it rather than just blatantly spying on them.
You can rely on library managers to do the wrong thing the world over.
