Pros

Working at Syneos Health has its ups and downs. One major highlight is the company’s unlimited PTO policy—a progressive approach that encourages balance and personal wellness without the stress of tracking vacation days. It’s a refreshing perk that many employees appreciate.

Cons

On the flip side, the contract-based nature of roles can introduce uncertainty. Contracts may end abruptly, and there’s often limited support or guidance for placement into new roles after a term concludes. This lack of continuity can leave skilled professionals sidelined despite strong performance.
