Bad leadership overshadows everything

Pros

- Depending on the business unit, you can find supportive, friendly colleagues. There is a strong sense of camaraderie at the peer level, which makes day-to-day work more pleasant. - There is also a relatively good work-life balance overall. However, it is sometimes unclear whether this is the result of a genuine company culture that prioritizes balance, or rather a consequence of inconsistent planning and organization, which can lead to periods of under- or over-allocation. - Decent healthcare benefits

Cons

- Clear lack of structure and transparency, particularly regarding promotions, bonuses, and compensation adjustments. Processes are inconsistent, often unclear, and sometimes feel arbitrary. In several cases, expected salary adjustments were delayed, minimized, or only granted after persistent follow-up. Bonuses are not always proactively distributed and may require employees to explicitly chase them. - Favoritism is a concern, with recognition and advancement not always based on merit. The culture at higher levels can sometimes feel unprofessional, with blurred boundaries that create discomfort. - Long-term employees tend to feel undervalued over time. Many leave after around two years, often because they see a very limited progression. - Overall impression that the company tends to optimize costs at the expense of employees whenever possible, which affects trust and long-term engagement. - Leadership tolerates or fails to address inappropriate, unprofessional, or toxic behaviors. It can go unchecked for years, with action only taken very late, sometimes for reasons unrelated to the misconduct..
