Another type of privacy issue occurs when employers enforce certain rules and procedures in the workplace that violate an employee’s freedom to do as they please.
A related issue is the amount of personal information that invidividuals post online - on Facebook, MySpace, Flickr, Twitter, and other networking sites. That information can often be accessed by employers.
Reasons Employers Can Collect Private Information
A company must have a defined business reason for collecting information about an employee; otherwise, that employee may claim that the information is unnecessary to the employer, and is therefore an invasion of privacy.
Information regarding, for example, sexual orientation, previous marriages, home ownership, or previous arrest records is not necessary for employers (unless, for instance, the information was needed for benefits administration or another occupational reason).
