To start, I've been a CW (Union Apprentice w/o going to school for 1 1/2 years). I got accepted into a Union program and I'm looking forward to our yearly rotation between Contactors, but I've worked for my contractor long enough they have taught me how to Trimble. I'm currently paid over-scale by $2.50 due to being one of the leaders on our current job's underground and having Trimble experience so they don't have to bring an office guy out to our jobsite. I'm looking for advice on transferring contractors come May and keeping my pay that is currently equal to a 3rd years pay. I don't necessarily want to continue Trimble or similar Layout work due to it being mundane. Should I tell my next contractor that I wish to be paid equal or more to what I was previously making and tell them about the Commercial work skills I have, leaving Trimble as a last bargaining chip, or should I emphasize it along with my current skills to get the best pay and hope I don't get stuck running Layout work.
In total is being able to solo run a Trimble RTS (with BIM files provided to me), as an apprentice, should I keep it secret until I can guarantee a better pay over-scale?
