As soon as you gain 2-3 years experience in a trade, my honest advice would be to move away as soon as you can. For those in trades, it is quite easy to find smaller and well respected companies with less corrupt management where you'll have a much better life.
Magna is a large corporation too big to fail and is [still] absolutely barricaded with lazy and unprofessional leadhands/team-leaders, supervisors and management that have been with the company for 15-20 years and seem to be invincible. It is an almost daily occurrence where excessive profanity, threats to "write you up" for nothing, and yelling amongst the aforementioned roles towards young/other employees takes place.
This is important to note because being "written-up" will have a negative affect every year on any "raise" you may get. Simply getting "written-up" for the simplest and most subjective things because management are on perpetual power-trips may mean you can't get that 1.00/year raise - but instead - now only 40 cents.
It is almost virtually impossible to "move-up" to management roles in this company unless you borderline bribe managers (i.e. buying them coffee and food on shift 'breaks'), or if you have a relative or family member in management.
Magna is also one of the very few companies I've ever worked for where it is possible to have within the same immediate family (father, mother, siblings) all work under each-other in subordinate roles. I have seen many times, a supervisor be a father, a leadhand be a son, a mother be senior HR, and so forth. This is absolutely ludicrous and should be absolutely not allowed.
