Aircraft Maintenance Engineer

Cons: Low starting pay (expect $12-15/hr nationally), high labor, high levels of responsibility, almost no room for error, poor union representation (if you even have a union), constant time crunch to "get the job done" by leads and supervisors, pressures from your bosses to deviate from the book, work long hours, work nights, weekends, and holidays, working in extreme heat and cold, working in confined spaces, high probability for layoffs, high probability of having to move (sometimes out-of-State) to find a job, but the biggest stress will always be "when will the plane be done"?
I wouldn't recommend this job to anyone that doesn't absolutely love aeroplanes and aviation. I love what I do and I wouldn't change it for the world, but that passion has to be there for the pros to outweigh the cons. You have to protect your license like it is your life. Don't back down to anyone trying to make you do something you're not comfortable with, and don't deviate from the manuals to satisfy anyone.
