A decade ago, left-wingers started using the phrase ‘zero hours contracts’ to refer to what had previously been known as casual labour or piece work. Once this pejorative term become widely used, Ed Miliband, then the leader of the Labour party, promised to ban them. Similarly, the phrase ‘no fault evictions’ was almost unknown to the general public until 2017 when pressure groups like Generation Rent and Shelter began using it and Jeremy Corbyn promised to ban them.
