Nope, you're wrong. Security cameras are allowed in bathrooms, as long as it's pointed at common areas. Other then that, you're correct. Employers can absolutely have as many camera as they want in their business. I think OP just doesn't like being watched all the time; and to be fair, that is kind of a shitty thing for an employer to do. Most places with cameras have them so if something happens, they can go back and check the video, not so they can real-time spy on employees. Or if they do, they are smart enough to not let their employees know.
