Fred.
Never been a union man and have never had cause to consider being one.
They have been a force for good, I believe, in the distant past, for the 'working man' when business owners would, if allowed, take advantage of their employees.
Whatever they may pay into the Labour coffers is, due to the diminishing numbers of their membership, far less than in their heyday. Considering what I believe to be the make up of this government they get the bulk of their money from other sources so the days of a pint and sandwiches at Downing Street is a thing of history.
Things have moved on....
