Retaliatory Culture

Pros

Salary, 401k benefits, comprehensive insurance

Cons

The manufacturing division (MMD) supports retaliatory practices by intentionally imbalancing workload, overloading non-favorited employees, in order to then write up and negatively review those employees per HR when they cannot perfectly handle multiple people’s workload. If you are fast tracked, you will have a good experience. If you are not, management will not seek to develop you, even if you ask for opportunities. The opportunities they provide will simply be more of the same work, which will then be used to justify not backfilling other employees, because you can absorb their workload but non of their compensation
