It’s from Australia, but the part that I have looked at so far could be useful for everyone trying to figure out how to build and maintain a workplace that supports mental health. (Check your local laws, though, as the legal references are obviously related to Australian workplace safety rules)
“These free online resources have been developed by Beyond Blue to increase understanding of mental health in the workplace and provide practical strategies to support you. Each resource takes up to 20 minutes to complete and can be used on desktop computers, laptops, and tablets.
Some of the resources are also Sharable Content Object Reference Model (SCORM) which means they can be imported into your Learning Management System (LMS) if you have one. “
Take a look and see if they help you too.
