PCAnywhere can accomplish this in real time. So can TightVNC, a free download. You will want to test either of these products. Certain configurations of PCAnywhere will change the remotes' desktop to a solid color, and there is a system tray icon that would need to be disabled.
These products are not meant to allow big brother access though. A better question is why you want to micro manage or police your coworkers/employees? I don't mean to start a philosophical discussion, but if you can not trust them then get rid of them. Don't waste your valuable time spying on them.
I have this technology installed and I use it for training and troubleshooting my remote branches. It works great for that.
You would find a better solution if you had a specific action you wanted to find out if they were doing. Like using corporate email for personal use, or surfing the web 6 hours a day. These things are better tracked with logs and proxy servers. Rather than micro managing people.
If you are a computer professional then stay in that profession, don't become a rent-a-cop.
