The non-sexist version of "mailman" is "mail carrier" or simply "postal worker." These terms are gender-neutral and can be used to refer to anyone who delivers mail, regardless of their gender. Using inclusive language helps promote equality and respect in the workplace.
Non-sexist language demonstrates sensitivity to others because you are addressing them for the person they are or for what they do and not for the "male" or "female" that they happen to be.
