Days off is great is you really need thrm.

The main problem in the US is that there is a very very limited of school trained tech. In fact I only know of one or two school in the Us.

Most dealer have to hire auto/truck tech and trained them. That is expensive and if they pick the wrong person it can be very costly.

Another problem is that after all that training the tech may get into a customer and gain the customer allegience to the point that if the tech leave that company the customer go to.

As for employment opportunies with no school training and many tech in their 40,50, and 60s with no younger replacement many company would jump at good tech.

My relative start is $9. hr during traing and 10 years later he at $23. hr.
The job market in the US is very open if you can get here employment will be the least of your worry.
