Common mistake on HN: the law is not logical.

The law says that if employers own the computers they provide to employees, then employers have broad latitude to monitor how those computers are used.

A different law says that only the recipient of a US Postal letter may open it. If you receive a personal letter at your office via US Postal Service, your employer cannot legally open it.

I'm not up to date on what the law says about FedEx or UPS.
