Angry depends on the heels I guess, I get crippling foot pain in totally flat shoes and the low heels I got for work actually made it so I could make it through the day. I don't really enjoy wearing them because they make me feel awkward (I walk a bit weird) but they are a necessary evil to enable me to do my job.
Probably different if you're looking at crazy high heels, never tried them tbh as I can't walk at all in them.
I don't know how Ash did 4 years there, people are pretty strong, but also anxiety is a hell of a barrier. This required her to come out at work, which is no easy thing in America.
How is this signing away anyone else's rights, the rights belong to anyone who feels they have a pressing need of an adjustment to a workplace rule, this could be any employee of any sex or gender.
Ash felt the reason she needed the adjustment was because of her dysphoria and worsening mental health, so she used that as a reason on the form. I assume if she felt her need was due to sexism she would have said that, although perhaps she would have received a different response from HR.
Perhaps that is the issue here? Why she had to use her trans identity, not why she did? The legitimacy of sexism as a reason for reasonable adjustments at work.
