I'm asking for a friend. She is a trans female and has decided to start her transition. She currently lives and works in Spain at a call center.
She hasn't disclosed the current situation since there has been no need at all. However, given time, the effects of the transition will start to be noticed and she'd like to be able to dress appropriately to the gender that she identifies with.
The relationship with management is not entirely ok, but as I understand it, if she were to notify, they should be the first to know about it. There are currently negotiations on position and relocation going on, but so far, I had advised her not to use this as a reason to justify her relocation or position. While it is convenient for her, I believe that bringing such a personal matters into the negotiations could leave her in a position where things escalate very quickly from disagreement to legal action. However, if she just says that it's for "personal reasons", it could not be alleged that any discrimination is taking place (and even better, she would not be discriminated against).
But still, the point is that they'll eventually have to know. When would the right time be for that? How should she approach it?
When and to whom should a trans-person disclose their situations in their workplace, in hopes of not affecting the business relationships?
