Did you know your workplace must, by law, post a copy of meeting minutes as well as a list your Occupational Health Committee members or the health and safety representative in your workplace? This must be posted in a conspicuous area where workers can easily access the information, and where it will likely come to workers' attention.
Reviewing this posted information is one of the ways you can stay informed as part of your Right to Know about safety issues in your workplace.
When you have a safety concern, you should reach out to one of your OH&S committee members to discuss. Some workplaces have an incident reporting line as well, and if they do then this is the primary avenue to bring such concerns forward.
For more information on OH&S posting requirements, here is a list by jurisdiction from the Canadian Centre for Occupational Health and Safety.
