The Importance of Trade Unions in the Future of Work

I don't think trade unions have much to do with the fact that children don't work in the mines or anywhere else anymore. We have a shorter work week for the last, the amount of time people have been falling steadily because we want to work less. It's a market force and that trade unions occasionally have asked for. If it wasn't happening through market forces, if it wasn't what people wanted, it would be very hard to get.
