Actions for the Knowledge
Commitment to the Health↔Work culture.
Decide what information needs to be available to everyone.
Arrange things so everyone knows where to find the knowledge they need, and are able to access it easily, quickly and repeatedly: think about making it available in printed and/or electronic format. You could also make posters.
Ensure the organisation and all in it have worked out (1) an approach to minimise health complaints (collectively through making the jobs good) and (2) to rapidly and effectively help colleagues who are struggling to work because of their health complaint (with temporary support and accommodation). That is, be proactive not reactive.
Find out if you've got the message across.
