Pros

NSF's mission is a worthy cause and they do very good work. There are a lot of very fine people who work for NSF in middle management and below, who believe in NSF's Misson. Benefits are better than average.

Cons

Company is run for the benefit of their most senior leadership. Take a look at the past few form 990s and you'll see NSF's leadership pay themselves significantly more than comparable sized publicly traded companies, while average salaries and increases are very low for the rank and file worker. They have a strong tendancy to get rid of their middle managers in January of each year to avoid paying them bonuses. Most NSF staff can name you a long list of people who are let go in January to the point it's gallow's humor.

Pros

None, a toxic workplace is not worth it

Cons

A newly hired director of toxicology has managed to turn this into the worst place I have ever worked in an astonishingly short amount of time. Her leadership is openly fear-based, condescending, and riddled with poor communication and blatant favoritism. Expectations changed constantly, were rarely communicated clearly, and were enforced through rude remarks and everyday belittling rather than actual guidance. Work-life balance has ceased to exist, stress is constant, and misery is now the default team culture. That’s not to mention mental health has plunged. People have stopped collaborating or doing their best work and focused solely on survival or avoiding becoming the director’s new target for her condescension and hostility. I actively dread work every day and am trying to GET OUT

Pros

Handful of good people caught up in a bad company

Cons

Hey you, seen an NSF mark, or an ad somewhere and wondering what the company is all about? Here's it in nutshell NSF -Abuses it's non-profit tax status by diverting funds abroad to build new offices and particularly directly into the pockets of it's executive team and board. -Embarked on a "transformation" in 2020 during the pandemic laying off hundreds at the peak of the pandemic when they previously said those people would be given new jobs, then they laid off the new staff that came in...then laid off the staff that came in after that. Rampant cryonyism ensued. Whole departments are built entirely off who they know. -Has very little to do with public health but sure talks about it a lot. NSF is all about the benjamins and will go after it despite the impact on public health (look up peanut corp of America...NSF client....) - Case in point, NSF has certified a ton of PFAS containing products, now that the winds have blown the other way they have a PFAS-free certification scheme. - A VERY unsafe place to speak up as an employee or offer suggestions to anyone who's a director or above. - Ask yourself, is a company that treats its employees so terribly really care about the public's health? Suuuuure they do.
