*3.3. Asociations between Workplace Demographic Characteristics and the Co-Occurrence of Occupational Health and Safety and Wellness Activities*

Table 2 shows associations between workplace demographic characteristics and the co-occurrence profiles of OHS and wellness activities. Increasing workplace size was associated with greater odds of a workplace being classified in the highest (profile 2) and moderate (profile 3) co-occurrence profiles compared to small workplaces without a JHSC. Large workplaces were estimated to have the greatest odds of being in the highest co-occurrence profile compared to small, non-JHSC workplaces (OR = 3.22, 95% CI = 1.15–5.89). Compared to small, non-JHSC workplaces, medium workplaces were most likely to be classified in the moderate co-occurrence profile (profile 3) (OR = 4.71, 95% CI = 1.42–8.74), followed by large workplaces (OR = 2.22, 95% CI = 1.05–4.52). Unionized workplaces were more likely to be a member of the highest co-occurrence profile (profile 2) (OR = 1.52, 95% CI = 0.48–4.88) or moderate co-occurrence profile (OR = 1.03, 95% CI = 0.33–3.27) compared to non-unionized workplaces, although these estimates were not statistically significant. Workplaces in the electrical and utilities (OR = 5.57, 95% CI = 2.24–8.35) and municipal (OR = 5.52, 95% CI = 0.91–8.43) industry sectors were most likely to be classified as a highest occurrence profile compared to the manufacturing sector, although the association with the municipal sector was not statistically significant. Workplaces in the electrical and utilities (OR = 7.67, 95% CI = 2.46–10.50) and municipal sectors (OR = 6.97, 95% CI = 1.80–9.06) were also most likely to be classified in the moderate co-occurrence profile. No statistically significant associations were found between scores for health and safety leadership and the likelihood of highest and moderate co-occurrence profiles. Workplaces rated highest for people-oriented culture were

likely to be classified in the highest co-occurrence profile (OR = 4.70, 95% CI = 1.59–5.26) compared to lowest-rated workplaces. No statistically significant associations were found between people-oriented culture ratings and the moderate co-occurrence profile.
