Avoid all sexual stereotyping as in Today's secretary is a busy woman.
Unless specifically requested by the individual in question, use chair or chairperson rather than chairman or chairwoman.
Use he or she or, the generic pronoun they.
Avoid terms such as maid service (make it housekeeping service); salesmanship (change to effective selling).
When impossible to change, use the slash method, such as foreman/forewoman (but why not supervisor).
Married Student Housing: Avoid using this term. Use university apartments instead.
