Where I work there’s employee male and female toilets, customer male and female toilets and one customer disabled toilet.

This colleague is non-binary, is not disabled, and uses the disabled toilet/ baby change (with their own Radar key) because they “don’t feel comfortable) using either the male or female toilets.

I mentioned to my boss that I didn’t think this was appropriate and got accused of transphobia and threatened with discipline. I was made to feel like I was being offensive and discriminatory for bringing it up.

We have many elderly customers and many young families who all also need to use it.

Was I being unreasonable?
