I have always masked and have been employed most of my life because of it. Worked a variety of positions in manufacturing - on the floor, warehouse, coordinator, inside sales. Worked my way up until my kids moved out and I lost my motivation to work so hard to try and fit in.
Rough last seven years or so and my new motivation is to not loose what I worked so hard to get. Not for the stuff, but the stuff does give me the option to be independent and to be in control. I'm recently went back into warehousing because the atmosphere is relaxed and it's mostly filled with other misfits. I do work that has a start/middle/end and nobody judges me, I can joke around, I punch in, I punch out. I guess this is my truest self because I enjoy it. Physical work is much easier than mental gymnastics and crashing on the weekend.
Honestly I never knew I masked (undiagnosed) until recently since I've been reading about autism. But I've paid attention and notice how differently I am depending on who I'm with. I also tried traditional office work recently for the pay but I can't do it any more. After a few months my differences really stuck out and I was let go, even though I could do the job, I never really fit in (setting was too social).
So I'm restarted near the bottom in a company that has lots of room to grow. I hope they recognize what I have to offer and over time give me more duties and higher pay (most past employers have).
My main roadblocks are office politics confuse me, that I need efficiency, and that I can't stand gossips. If you're like me I'd advise getting a job where you have some responsibility, that way you have more control over your day. Since nobody really knows the exact details of what you are doing or the order your tasks need to be completed you can be somewhat flexible to suit your moods. No one really keeps tabs on you, or will question why you walk away from your desk, or will interrupt you (they will email though which is soooo much easier to deal with).
Good luck with the job hunt!
