Pros

There are no pros to working at GAF.

Cons

Where do I start? Since GAF corporate HR trolls Glassdoor to find and root out the ones which would shed light on the truth about their toxic company culture to silence them and then manufacture (pun intended) ways to discipline or terminate them, I will have to reveal as little as possible about myself since I'm a current employee. I'm searching for other opportunities, and I know MULTIPLE colleagues are doing the same. I'm in HR, and morale is low among MANY human resources professionals. Many veteran HR talents have left. Talent Acquisition is freaking out because the company reviews here on GlassDoor are horrible and, surprise, prospective talent reads these reviews. Employee engagement surveys have been postponed multiple times, but even if we eventually have them, there will be no accountability for anyone at the corporate level. The toxic culture will be blamed on the manufacturing locations. I literally laugh every time someone mentions GAF's corporate values: Empower, Evolve, Connect, and Inspire. They must not apply to directors or above! Not a single one of them are embodied by leadership and just when I think it can't get any worse, it does! However, until I get another job, I'm here as GAF just sucks more life out of me. Before I go, let me just vomit a bit over the HR Bi-Weekly meeting. It's embarrassing. It's an orgy of insincere accolades where everyone has to turn their camera on and smile and cheer. I wouldn't be surprised if someone dropped in and tried to start selling Plexxus! That's the vibe it has. If you're considering GAF, whether you be an HR profession, engineer, or in operations, run, don't walk, as fast as you can away from this company.

Removing WFH

Pros

Coworkers are great. Decent amount of learning opportunities.

Cons

It is extremely disappointing that the CEO has decided to start removing work from home days. At a time when there is a national housing crisis, many people cannot afford to live within close proximity to the Parsippany HQ. Removing WFH days greatly reduces work/life balance, and increases costs in employees' daily lives. Company morale is dropping quickly.

We understand that shifts in workplace expectations can be challenging, and we’re committed to supporting our employees through this transition. Our move to a 4:1 in-office schedule reflects our belief in the power of in-person collaboration to drive innovation, connection, and long-term success. While the policy will remain in place, we’re actively working on ways to make the in-office experience as productive and positive as possible, and we welcome ongoing dialogue to help us do that well. We value your contributions and experience with our organization, and we know that adapting to workplace changes takes time.
