That is one of the main reasons that people join and stay in a union. When asked, 70% of new trade union
members considered health and safety a ‘very important’ union issue – more even than for pay
There is a wealth of evidence for the union effect on safety, that has been produced over the past 10 years or so, both in the UK and abroad. In 1995 a group of researchers analysed the relationship between worker representation and industrial injuries in British manufacturing. It found that those employers who had trade union health and safety committees had half the injury rate of those employers who managed safety without unions, or had some other process to involve staff.
