I'm just about done creating my website at RateAWorker.com (all content is still offline, but will be up in a few days).
But now I'm wondering if this website would even be legal? Users can rate their bosses and workers on a scale of 1 to 5 based on categories like attitude, competence, and fairness, leave an overall rating and some comments.
My friend told me this might invade worker privacy rights:
"when you are applying for a job... YOU choose which references you give out... "
"Everyone has the right to a job... and if you slacked off somewhere you have the right to have that kept secret. "
She also pointed out that people could get fired over ratings and comments left on the website.
I anticipated there might be some legal complications from such a website, but now she really has me thinking

There are other websites in existence that allow people to rate professors, teachers, lawyers, doctors, mechanics, realtors, and restaurants. These websites are all legal, so wouldn't my website be legal too then?
Any replies and opinions on this matter would be GREATLY appreciated. Thanks.
EDIT:
I've seen references to these websites on other rating websites:
