Pros

Salary was somewhat fair, however minimal bonuses / raises. Ultimately the toxic culture outweighs nearly every potential pro

Cons

- Poor people management and lack of accountability at the management level - Disrespectful communication from leadership, including being talked down to and undermined in front of others - Feedback culture feels punitive rather than constructive - Employees are not supported or treated with empathy during layoffs - HR processes are inconsistent and require excessive follow-up, essentially nonexistent

Pros

still having a job, co-workers, work-from-home

Cons

Come to work here and you'll spend all your time justifying every minute of your workday. You cannot brainstorm with others to improve outcomes for the client if you don't have a billable code to charge the discussion to. Which is probably fine honestly, because the corporate-think culture cannot tolerate new ideas anyway. The current CEO says absolutely nothing when he talks except platitudes about working hard, giving more and more and more and more each month, not settling for less (than you can give), being the best the company can be, etc. He doesn't spend any time getting to know employees or learning about actual problems and is protected from the harsh reality of working for Syneos by 62 layers of managers. He will continue in the same vein until he leaves for another CRO in a year or two; on to an even bigger paycheck. Employees are expected to work more for less, work late and come in early, and be better than their managers are. If you don't have a lifetime of experience working at Syneos, you will not promote, and if you are talented and smart you will be gaslit into thinking you are never going to be as good as the people that have worked at Syneos since birth.

Pros

You get a Paycheck but that’s it

Cons

This is the worst company I have ever worked for in 15 years of being in healthcare. Leadership is extremely rude, untrustworthy, and manipulative. Unrealistic expectations from workers.
