Outsourced to death

Recommend

Pros

Relatively low pressure work environment, for biotech.

Cons

Seemingly every internal service has been outsourced without any attempt to centralize and streamline the access to these services. What employees are left with to accomplish anything is word-of-mouth, old hyperlinks, and direct contact emails for contractors who never stay longer than a year. A third of an employee's time is spent navigating bureaucratic bloat and facing headwinds from contractors who don't care about accountability or quality.
