Last month the Supreme Court of the United States decided your employer has a right to every single thing you do on your work electronic devices. Every. Single. Thing.
Privacy at work does not exist. In the case that was heard, the employer paid for only half of the cost of the pager and they still had access to everything.
Keep that in mind as you spend time behind the computer and on your Blackberry today.
