Pros

High-volume experience, but at a devastating cost to your mental health.

Cons

The Training Department culture is characterized by strong-arm management practices and systemic gaslighting. Suppression of Positive Feedback & Gaslighting Employees can expect consistent undermining. Feedback is overwhelmingly negative, with little to no acknowledgment of positive performance. Even when peer feedback or course evaluations are highly favorable, leadership focuses exclusively on “improvements,” creating an environment designed to keep employees off-balance and erode confidence. Coerced Performance Reviews Annual review processes are handled in a coercive manner. Employees who question or request time to review their evaluations are pressured to sign immediately, with implicit or explicit threats related to job security. This practice appears intended to silence dissent and establish questionable documentation rather than foster fair performance discussions. Protected Toxicity Leadership has communicated that certain long-tenured supervisors are effectively “untouchable,” regardless of reported concerns about bullying or unprofessional behavior. This creates an environment where toxic conduct is tolerated and accountability is unevenly applied. Lack of Recognition & Mismanaged Engagement Efforts The Training team receives minimal appreciation compared to other departments. Engagement budgets appear underutilized or mismanaged, resulting in sparse and low-effort recognition. Even basic morale initiatives, such as welcoming new hires, are delayed or consolidated in ways that feel dismissive. Surveillance Culture & Peer Sabotage The department operates within a “fake nice” culture where collegiality feels performative. Informal conversations are monitored, and peer feedback mechanisms are used punitively rather than constructively, discouraging trust and collaboration. Two-Faced Leadership & Ineffective HR Support Management presents as supportive on the surface, encouraging openness, but later uses employee disclosures against them. HR does not function as a neutral resource and instead appears to protect leadership rather than address harmful practices.

Pros

Penumbra practices what it preaches. This company is so successful because of its leadership consistently pushing a positive message to its employees. We do not engage in the same old sales tactics and pushy behavior that others in the industry are known for. Penumbra sales force is second to none because of their commitment to their physicians, staff and the mission itself.

Cons

Very high standards and expectations from physicians and allied staff.
