Ok, but corporations also lie to and defraud their employees all the time. In ways large and small.

Nobody is entirely honest to everyone about everything in their workplace. You really think everyone is actually sick on every single sick day, or that every single doctor's appointment on their calendar is a real doctor's appointment? People never make excuses to their manager that are lies? Managers never lie to their employees about a justification or a deadline or a promise or a policy?

Workplace dishonesty is everywhere. Because workplaces are made of human beings. It's just something you learn to manage in a realistic way. People are mostly honest, but they're never entirely honest.
