I think to protect retail slaves on the whole, more people should be educated on the laws. Legally speaking, there SHOULD be a sign posted someplace in the employee area telling them their rights (under Federal Law).
Remember being in a Right-to-Work or Union State means nothing, Federal law trumps State law.
Someone one time told me that his company refused to obey OSHA regulations because they were in a “Right-to-Work” state.
Two major problems, 1) “Right-to-Work” ONLY means you can not be forced to join a Union, 2) OSHA IS FEDERAL LAW, and again trumps state laws.
Laziness (or naivety in believing what you are told) is no excuse for not learning the Law. Knowing can help protect you from scumbag bosses.
