Extremely Toxic Work Culture

Recommend
CEO approval
Business Outlook

Pros

Salary seems to be the only positive point here

Cons

Work culture is Extremely Toxic (Let me explain a bit: They force you to work more than daily working hours (more than 10-11 hours) and then you are supposed or forced to work on weekends also, not one or two weekends, but mostly all of them. If you refuse sometime they treat you like you have done something illegal, and if you are lucky enough, you might get threats from very high level management that they will throw you out, also will destroy your career). I definitely salute to the people who are still tolerating those things and working there. If you don’t need any personal life satisfaction or want to study how toxic a workplace could be, joint there in PV department. There was not a single day when i was well mentally while working there. Don’t believe me, just Go and ask anyone working there.

Pros

Remote work Great co workers

Cons

Hired for a REMs program that was ending in October of 2025. FDA pulled the plug early, leaving over 50 employees jobless. Syneos solution? Nothing. No severance, not even I’m sorry. The best part? They scrambled and selected 50 of us to go to another REMs program before the contracts were even signed. Got an offer, 24 hours later, find out they aren’t signing the contract and our jobs were done. They had nothing else to offer. They do not care. Select who they want for positions, even when they say it’s “fair”. Bonus payouts take months, and if your manager doesn’t like you? You’ll get docked dollar for dollar on that bonus. Stay. A w a y.

Company going downhill

Business Outlook

Pros

Not much to say. The ability to work remote, although the new CEO mentioned he wanted to bring people back into the office.

Cons

The salary is low compared to the market, the annual bonuses and merit increases are a joke (they don’t even cover inflation), no career growth, the company has some of the most toxic people I’ve ever worked with in my professional career, lots of company politics and dancing around people’s toes, leadership is stuck in their old ways and nothing ever changes, HR doesn’t care about you. There were 3 different CEO’s in my less than 2 yrs at the company if that is indicative of anything. Toxic. Toxic. Toxic.
