I am in "the trades" in a very conservative part of the US (Florida). Fortunately, I am in the management end of it and have several college degrees related to the industry. I also live the double life thing in order to maintain a relatively high income. This has defiantly contributed to the maintenance of my marriage. I have long hair, been on HRT for a decade, and had my beard removed. If asked directly, I will not lie.
I have found that if you are a good worker management will try to "fit" you in. You just need a superior set of skills, experience, and a willingness to take on the hard tasks. Maybe that isn't the best "forever" solution, but could it be, perhaps, the best step to get to your goal? Transition is expensive, and the trades can be a good way to finance it. It may seem slow, but better to get there in a while than to jump ship too fast and end up underwater. Just keep your eye on the prize, and work for it.
