Toxic Culture in Audit Team

Recommend
CEO approval
Business Outlook

Pros

Great opportunity to learn to segments of Mars.

Cons

- Toxic Leadership across the executive level. Toxic by creating an environment of fear, stress and incompetence. Leadership is, specifically in the Newark office is inexperienced and self concisious, which creates a toxic environment. - When I was working there, team members were vomiting prior to work, seeing therapists and taking medication just to deal with the situation. - HR did nothing of the situation even after 4-5 people complained.
