Very polticial

Pros

Ok salary and benefits. Good pension matching scheme. Canteen and onsite parking. Good opportunities for travel.

Cons

Quite political. They tend to pick their favourites and promote them. Promotions are given out based on exposure rather than performance. Business seems to think that their mission is greater than simply producing chewing gum and as such they are quite arrogant. They also don't treat suppliers very well.

Great Place to Work

Pros

Great benefits, culture, and brands.

Cons

Large company, slow to make decisions, outsourcing & shared services puts a lot of clerical work on associates. All of this can stifle creativity.
