Is there a reason you have characterized this incident as a gender issue?
Was the poor work the work of the nurse who heard you and chewed you out? Do you often criticize the work of your coworkers in a nonproductive manner, expletives or no?
Did you say anything else before saying “fuck” to your coworker, or before she chewed you out? Do you think you were on good terms with her before this incident?
Are you listening to the specifics of your coworkers’ complaints? What are they asking you to do differently?
All you’re doing is telling other trans people that their gender recognition is conditionally valid only on their good behavior, and that it can be revoked if they piss you off. Maybe consider why this would make trans people feel unsafe with you, even if they are on your side politically.
