Workers trust their unions. They trust the people who they have elected or who have been appointed on their behalf to look at health and safety issues. If that whole committee is taken out and if the person they trust is taken out of that equation, then who do they turn to, particularly when the issue may be the employer or their supervisor?
The whole point of it being a joint committee is that either side has people there who they can trust and who they feel comfortable speaking to about the issues that may arise. Again, if you take that out, chances are, as we've heard from a number of people, that they won't complain, and the situation will fester and get worse, because they will feel intimidated to come forward and to say anything about what's happening in the workplace.
