The article looked at how being in a union affects wages and job performance in the UK. They used data from surveys to see if union members earn more than non-members. They found that union members in the public sector earn more than non-members, especially at the bottom of the wage scale. In the private sector, there was no significant wage difference between union members and non-members. The study also found that when the National Minimum Wage was introduced, more workers joined unions to protect their jobs.
