Pros

The coffee machine? But I'd rather get paid more.

Cons

Company sets out asinine budgets and then expects technical staff to work off the clock to make up the difference. The place is an absolute puppy mill, report after report written poorly by EITs are all over the industry. The only reason I think this shop gets hired for anything is because they have the size, and can make on to bigger companies and government agencies that they can handle the work others can't.

Pros

Decent wages, fair treatment, felt respected, lots of hours.

Cons

Because of the state subsidy to my hourly rate, the overtime rate was significantly less than if the company had been paying the full amount for my hourly rate in the first place.
