Pros

The organization’s mission has historically been meaningful, and for many years I worked alongside committed employees who genuinely cared about the work and each other.

Cons

I was a tenured employee who experienced several restructures over my time with the company. In my experience, the most recent restructure—following changes in executive leadership—was the most challenging and had the greatest negative impact on culture. Since that transition, leadership decisions at the executive and Senior Leadership Team (SLT) level contributed to what I experienced as an increasingly toxic and high-pressure work environment. The organization became heavily focused on revenue and micromanagement, often at the expense of employee development, trust, and the company’s stated mission. Additionally, SLT introduced a “Courageous Leadership” program that, in practice, created pressure for managers to rate employees lower during performance reviews. This approach limited raises and bonuses, even for employees who met or exceeded their goals, which was demoralizing and eroded morale and trust.
