I've been working with BTS for the last 6 or so months now. When I first read this thread prior to getting the job, I had my doubts too. I decided to go for it anyways though.
Honestly it hasn't been all that bad. Like others have said, some days are rougher than others. Expect to stay past your scheduled shift sometimes (overtime). For me anyways, the learning curve was pretty steep at first. The 6 weeks of training was great and all but I feel like they didn't provide nearly enough 'mentor rides' in order to really get a feel for the job. Once the classroom stuff is over and you're thrown out in the field, you've gotta stay positive and push through it. You won't know wtf your doing, but it gets easier
At this point I can say I'm enjoying this job. If you like working on your own, this job provides a lot of freedom. Each day is definitely unique, there's lots to learn and lots to see. Each day is like a friggin treasure hunt though looking for all your opi's, peds, aerial terminals, etc
btw I've been getting steady 40 hours every week + 8 hours forced overtime. I've been doing four 10hr shifts, one 8hr overtime shift, and then 2 days off. I have over 200 overtime hours banked which I can cash at any time. That's pretty awesome
