Single employee is nothing. Union of employees can grind the company to the halt and needs to be negotiated with. Unions popped up around 19th century in Europe, when unregulated capitalism was the policy of the day with consequences like working 16 hours a day, 6 days a week for meager pay in dangerous environment able to maul you or crush you when you done smallest mistake. Same like pain is a response to damage of your body, union is response to abusing your employees.
