I haven't quite come out at work yet, but will be doing so within the next month or so. I am planning to meet with one of the Human Resource reps, one that I have worked with quite a lot, and talk through any existing procedures or protocols, so that we can agree to a date. I imagine that I'll probably want to take a few days just before, maybe as little as a long weekend, prior to my actual transition, giving them time to prepare with whatever sort of awareness or preparations they plan for in these cases. (I imagine they have something written down, although I haven't uncovered it in my policy searches so far). I've already taken care of my identity documents, like my Social Security card, driver's license and passport, so the remaining changes will mostly just be within the company systems and records.
If this thread is still running a month from now, I'll be able to fill in the gaps with actual events versus expectations.
