Unions
In the UK, the Unions have in the past, brought the country to its knees over the most puerile of arguments. Their power was smashed in the 1980's by the evil Mrs Thatcher, but even she could not obliterate them. This is a good thing. I am not in a union, due to a falling out many years ago, but this does not mean that I am anti-union. I am definitely against unions being capable of causing nationwide chaos, but equally I feel that some restraints need to be in place to curb management abuse of people. In a capitalist country, the unions are often the only organisations with the clout to stop virtual slavery, employee intimidation and downright cruelty by management bent on 'bonus at any cost'.
People have the capacity to be evil. Management have the power. Some form of restraint is necessary. There are always two sides and circumstance determines which side you're on. From a management perspective, unions can be evil, and from a worker's perspective, management can be evil. For any semblance of fairness, we need both.
