Pros

1. Flexible hours 2. Opportunity to cross-train with other lab departments

Cons

1. Discriminatory; only friends of supervisors and higher management are promoted 2. Toxic environment where verbal abuse is tolerated and inappropriate remarks and actions are not addressed 3. Upper management will intentionally slander you to other departments or to other potential employers (DO NOT use them for reference) 4. Overall one of the worst working environments I have experienced
