Working in the U.S.
As a retired mechanic and qualified avionics tech- the pay is terrible.
Most co.'s have eliminated fixed retirements, except those you fund yourself. The unions are not beneficial to the rank and file. The knowledge level is lower because the requirements are also. Most are not willing to educate themselves in system knowledge. The industry is
slowly coming to realize anyone with real skill and experience is leaving,
due to earning capacity. Many are retiring early, the young guys are going into other fields with all the skills. Most of the carriers that went into bankruptcy lost most of their skilled people. Very few were absorbed into other carriers which drove payscales down. Canada is in the same shape. I've been thru GA, Corporate and 4 different Airlines
since the industry was deregulated. Fortunately my skill levels were far above most, so I was able to make a modest living. Anyone looking to work in this country in Aviation is in for a very rude awakening. The job market at this time is extremely limited also.
