Pros

Good pay, interesting projects, coworkers are genuinely smart

Cons

Working at Syneos Health as an Associate Program Manager was one of the most disappointing professional experiences I’ve had. The role is sold as a growth opportunity, but in reality it’s a grind fueled by poor work-life balance, toxic communication, and a culture that actively undermines professionalism. The work-life balance is abysmal. Long hours are not the exception, they’re the expectation, and there’s an unspoken rule that being constantly available is part of the job. Burnout is normalized and even joked about, while any attempt to set boundaries is quietly punished. The workload routinely exceeds what’s reasonable for the role, yet support and staffing rarely scale to match expectations. Even worse is the culture among coworkers. Gossip is rampant. Colleagues frequently speak poorly about one another behind closed doors, creating an environment where trust is nonexistent and everyone feels expendable. Collaboration feels performative at best. You’re never quite sure who’s smiling to your face while criticizing you to management or peers later. This behavior extends beyond internal teams. There is a deeply unprofessional habit of talking down about clients and vendors, often openly and casually. Rather than fostering partnership and problem-solving, the culture encourages blame, sarcasm, and finger-pointing. It’s corrosive, and it sets a terrible example for junior staff trying to learn how to work in a client-facing industry. Overall, the experience feels less like working for a healthcare solutions company and more like surviving a corporate pressure cooker where negativity is ingrained and burnout is inevitable. If you value psychological safety, professionalism, and a life outside of work, this role—and this culture—is not it.
