The employee’s job is to deliver value to the business. The business’s job is to enable the employee to deliver that value. Mentorship, fair wages, career growth oppurtunities, etc. Many businesses fail on their end of the bargain. Its no wonder the employees are repaying the effort in kind.
A little empathy goes a long way. There are some truely shit evil people in the world, but most people are good people who werent given the same chances, lost their way, etc.
