well, i just started hormones yesterday, so im nowhere near being able to switch. but there is another employee im aware of who is just starting to "pass" and is able to use the ladies room, but still choses the family room whenever it is available. actually, pretty much everyone at the store picks the family room over either of the gendered bathrooms if its empty. im in california though, in a fairly laid back area, and work at walmart that recently added its own anti-discrimination/harrasment protection at the corporate level.
