Pros

The very few benefits and good colleagues that remained after our company was acquired by TFS.

Cons

Horrible communication from leadership and HR. CEO publicly and proudly supports the same administration that has helped tank the biotech industry in the US while the CEO continues to do layoffs and blames it on the state of the biotech industry. Company claims there are opportunities for internal advancement but no one I know who has tried has been able to transfer internally and there is no clarity on how to navigate the pay band structure. They claim to factor both inflation and merit increases into yearly raises however raises don’t even keep up with inflation alone.
