Pros
Good company if you are prepared to give your self over completely to it. You can earn the money by working plenty of hours and give your family a good start in life. It's is possible to get to the top in the company. Good products that will always carry the company through.
Cons
Like to call themselves an ethical company but one thing I've learnt over the years is that I want to work for a moral company. By ethical company I mean they know what is right and say the right words but do something else. I once filled in an "anonymous" survey and the following day received a phone call and was questioned on what I had put and then got the survey back to reconsider what I had put. To advance you have to learn how to play the game, it's not about knowledge or skills it's about networking. This has gone on for as long as I have have worked for 3M till now it's ingrained and part of the company. Those at the top have got there on the whole by this means and don't know how to spot knowledge or skills because they have never had to use them. Be careful what you say on here as they do monitor sites like this.
