Pros
Magna is a decent company if you are starting out in an industrial trade - such as: Tool and Die Maker, Millwright, Industrial Electrician or Weld Technician because of the unlimited overtime which gives you the opportunity to learn. Benefits are average to slightly above average in comparison to other similarly large corporations. They have gotten slightly better in recent times as well which is a plus (particularly for dentist and optometry subsections). Profit sharing is a plus as well, however, mostly overrated unless you've been with Magna over 10 years. RRSP-match contribution up to 3% (if you pay minimum 6% into your RRSPs) is also a plus. Magna [Rogers] phone plan is also a plus although is getting less and less of a good deal through time as Rogers continues to make corporate phone plans worse.
Cons
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.
