Are employers allowed to tell an employee to use a restroom that does not match the person's gender identity or presentation?

The Answer to that is, No. transgenders are allowed to use the opposite-sex restroom if they feel comfortable or, Safe. and for example; if a Man that is a transgender woman enter the men's restroom, they might get some looks and discrimination. it's just safer and takes less time to argue. A transgender person should use the restroom that matches who they are.

There is also no rule that a person must look a certain way to use a certain restroom. This kind of “gender policing” is harmful to everyone, whether a transgender person, a butch woman, an effeminate man, or anyone dressed or groomed in a way that doesn’t conform to someone else’s gender standards.
