Pros

Fridays are still remote. That's it Just that.

Cons

The new CEO has effectively killed what was so special about this place. He's fired anyone who knows anything about making our product, development of new innovations, what makes us special to our partners, marketing which was one of the things that made me proud to work here, and taking away the cool stuff that made GAF different.
