How to destroy a team in 1 year - Infrastructure Engineer FARFETCH Employee Review

At first years we all worked as a team, anybody who need help inside infrastructure or from engineering teams we would collaborate as #todosjuntos motto. Since about 2 years when new leadership was appointed at infrastructure this is like trenches everywhere. Nobody collaborates. Toxic environment. New people hired which behaves like ownerships of truth and only takes care of themselves. The same happens with the Infrastructure leader which only relies on his teammates / friends. There's lost of contact with any engineering team, and leadership just pass the day in office chatting with VPs and Heads without knowing why the hell so many important people are leaving the company.
