but the unions are mostly effective in the public service. Its why most public servants are union members, and most private sector workers are not. A lot of people who work in the private sector cannot go on strike - people would just shop elsewhere or whatever if they did.
O'Connor and the other union bosses pay themselves 3 and 4 times the average private sector wage. They were responsible for doubling the public sector pay + pensions bill from 9 billion to 18 billion in the space of just 10 years.
But Union Leaders are not paid from the public purse, so in that sense unions are "private sector" organisations.
The taxpayer does not pay Jack O'Connor's salary any more than it pays the salary of any overpaid CEO in the private sector.
