Withdrawing one’s labour in order to gain better pay and conditions is a basic tool in the armoury of the wage earner. Making sure they cannot is the basic tool of governance. It is essential if you are going to require some people not toe strike, or some people not to have the ability to strike effectively to make their point, that they are given additional safeguards.
Today we have a wave of strikes in the UK because people are working flat-out and not being able to pay their bills. This is a failure of government. Nothing less. We must ensure workers who may not strike should be looked after so such a situation never arises. That means those who oversee those who earn wages must care more.
