Once you learn a trade they can never take it away. Im just returning back to HVAC after a working for the railroad in a railroad town. A dream job in these parts. Out of the blue they came in a shut the yard down, and cut 200 plus jobs. I was out of work 2 or so weeks. While most of my bro's are loseing there trucks and houses I didnt miss a paycheck. Stick it out and take in as much as you can. Even if you change careers later on down the road knowing a trade can be a lifesaver.
