Bad leadership, declining culture, no work-life balance

Pros

Good benefits, competitive salaries, strong 401(k) match. PTO used to be generous before it was changed to "unlimited".

Cons

After significant leadership changes, the culture declined sharply. Employees are afraid to speak up because of retaliation. HR fails to protect employees. The culture shifted to the culture of fear and mistrust. The shift to “unlimited PTO” significantly worsened work-life balance. Time off depends heavily on manager approval, often discouraged even when requested far in advance, and unused time cannot be banked. Many employees experienced this change as negative despite how it was presented. A common theme shared by many who have left is poor leadership, no work-life balance, and expectations to be available 24/7 with little recognition. There is as clear gap between stated values and actual reality.
