General Motors

Lots of corporate holidays and a good vacation amount.

401k matching is good but hampered due to a 3-year minimum vesting period.

Low health insurance premiums.

No growth opportunities. Management actively discourages their employees from moving to different departments. For them, it's more important to retain employees in their own group, without regard for their career growth.

Lots of politics and no real work in some departments. IT managers force developers to find work, bypassing the Business Analyst channels and creating chaos and confusion for everyone. Toxic culture involving belittling other groups' achievements instead of fostering collaboration.

Salary and compensation for senior folks are not up to par with market rates.

Red tape everywhere. Incompetent "shared services" people who stifle innovation and introduce unnecessary processes everywhere.

Trim the layer of fat that is in the form of so many managers who contribute minimal value, take all the credit, and have no interest in growing their teams.
