NSF WTF is right

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.

Bad management leads to high turnover

Pros

Besides the benefits not really any

Cons

Working as a lab tech at NSF was one of the most frustrating and demoralizing experiences of my career. From the very beginning, it was clear that this was not a healthy workplace. The HR department is completely useless—offering zero support when serious issues arise. If you raise any concerns, they either brush them off or mysteriously disappear from the conversation entirely. The management culture is even worse. Managers openly play favorites, creating a toxic environment where advancement or even basic respect is determined by how well you fit into their clique—not by performance or professionalism. If you’re not part of the inner circle, expect to be undermined, ignored, or worse—scapegoated when something goes wrong. Turnover here is sky-high, and it’s no mystery why. New employees are constantly coming and going, and those who stay longer often do so out of sheer necessity, not because they believe in the organization. Training is minimal, expectations are unreasonable, and there’s no recognition for hard work—unless you’re one of the favorites. Worst of all, managers are completely exempt from consequences. No matter how poorly they behave, they always manage to twist the narrative to place the blame on someone lower down the ladder. It creates a culture of fear and mistrust, where employees are afraid to speak up or advocate for themselves. If you’re considering a position at NSF, especially as a lab tech, do yourself a favor and keep looking. This is not a place where integrity, support, or fair treatment exist.
