IANAL, but as far as I read into the situation, employee monitoring is a very dangerous field. There are exceptions, however, such as company-provided http(s) proxies and more concrete monitoring or investigation when suspicion arises (I know of two cases where employees were suspected of consuming child porn and they were both monitored as well as having their hardware seized). Lastly, the companies or specific malicious admins might simply not care about the legality and still monitor you - either for company reasons or simply to stir through your data. If they have admin access to your computer, it's simply not your computer.
