The insurance and retirement benefits were terrible.
The CEO was detached and seemingly clueless about the day to day operations.
Horrible people would get promoted all the time because they were sycophants.
The company made reckless forays into doomed R&D projects, wasting who knows how much money.
Layoffs and firings were extremely common, with "right-sizing," an annual or biannual occurrence.

The executives all had a habit of throwing others under the bus instead of admitting their own mistakes.
The culture was depressingly Machiavellian, with managers and supervisors all waging their petty little wars.
