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.

Avoid entirely.

Pros

Some decent coworkers, travel compensation is good, and starting salary is high.

Cons

Leadership is glorified and put on a pedestal with one simple motive - SELL, SELL, SELL. In return subordinates are treated with very little compassion and expectations are set unrealistically high. Their idea of "onboarding and "training" is a laughable joke. Very chaotic and tumultuous environment. Look the other way.
