Do some research on your company's internal website to see if they have any guidelines for transitioning, many of the larger companies do. I found my company's transition guidelines and read them several times. I knew I was in a safe place, but I wanted to wait until just before I believed the changes were going to become noticeable. I was on HRT for nearly seven months before I told anyone at work. Per our guidelines, any communication related to my transition must be treated as confidential. My manager is in another state, so I sent him an email outlining the situation. His response floored me, I could not have asked for a more perfect response. With my consent, my manager contacted an HR representative who heads our companies LGBTQ employee resource group. We discussed my rough timeline for coming out, and I was told that I was in charge of my transition. In a company of over 30,000 employees, only four people know about me - my manager, one HR rep, one benefits advisor (all in another state), and one co-worker who sits near me. I just had to have someone local to confide in, and she has been a real blessing. I am not out yet, but that day is coming soon. Before my company can update the email and payroll systems I must be able to provide a copy of my driver's license and SS card with my new name. Hopefully this will occur sometime in late March.
