Must of misread your post Alexia. I thought you weren't on hrt yet. I was asking whether it was an option for you to do it secretly. But I see you have been on it for over a year, so they must be aware of your progress with hormones. Well, even if your parents aren't happy about your transition, it seems like there may be some hope. I mean, you are living with them and have been on hormones for all this time. Perhaps they are reluctantly accepting this, but at the same time trying not approving of it. If so, I think time can heal some things in that area. At the very least, I really hope so.
And good on you for making those suggestions. Seriously, their hr department is run horribly. I'm sure you can find a new company that has more sensible policies.
