Very long hiring process
No work life balance (they tell you in the interview that they don't do mandatory overtime- thats a lie)
12 hour shifts
Everyone starts on night shift
Hard Work, No work life Balance, 60 hour work weeks, Forced last minute overtime and Weekends, Unreasonable production rates. Is getting harder to keep up with production rates. Moving towards Amazon Style of management. Too Much FAVORITISM.
Great health insurance, time off, disability, etc. Operators at the plant are friendly and easy to get along with, most people understand that the younger engineers move around a lot.
Cons
Process and Product Engineers tend to have a lot of overtime during night hours or early mornings when you get calls from operators and they need help (this is unpaid of course). Additionally, if there are new product trials, you will need to put in a lot of extra hours that cut into personal time or rest hours. 3M also places new engineers right out of college into the more undesirable locations, which means that not many people stick around for long.
Very simple work flow: Picking pallets is not difficult and becomes muscle memory fairly quickly. The longer you're there and the more you prove your ability, you'll be put into other job functions that are easier/less physically taxing.
If you want to make a career out of this, 3M is almost always hiring internally. Most people in a Lead position or in the office started out as a Picker.
Cons
Forced overtime. This could be considered a pro by some but if you value your free time then it probably isn't.
You will be exposed to cancer causing chemicals, there is no job security, the company handles every situation completely differently so you will never know what to expect,and you will be forced to work mandatory overtime consistently.
