Yes, if you are working in the construction trades, you rarely stay in one place very long. There are some electricians I know who have worked for one contractor throughout their entire career and even some that have worked at the same place but most of us are there until the job no longer needs us then it's on to the next job.
There's some good and some bad with that. If you hate the work, the location, the foreman or the contractor, you know it's only temporary. But when you get that really sweet job, you hate when it ends. I've had a few of those. And when times are good, if you don't like the job you're on, you can always go to the hall and get another.
On the downside, construction workers aren't very understanding about gay or trans stuff. We have a few members who are lesbian and that is tolerated but if you're gay, you'd better have thick skin. And if you're trans - forget it! One threat I got was "Accidents can and will happen." Most of the so-called macho occupations are pretty much the same. "This is man's world!" And, no matter what anyone says, women really are only tolerated, not accepted.
