Pros

Many learning opportunities. Flexibility within the organization for decision-making and ideas. An open-minded mentality gives you a voice, regardless of your position. Networking opportunities are not uncommon; many plant visits, employee resource groups, and company events facilitate this. Friendliness is a driving force in an otherwise productive environment; everyone is always willing to lend a hand and share their knowledge. Recognition; You will be recognized for your work, no matter how minute the task. Overall, this will put your foot into a door where you'll be welcomed and encouraged to grow, with support from all sides.

Cons

Need more flavors in the water dispensers!

Pros

Cafeteria food is decent and the building is nice

Cons

This place has really gone in the gutter over the years, hard to see how it will turn around. If you’re thinking about joining, the industry is Good but I’d stay far far away from GAF
