*2.4. Control Site Activities*

For the control sites, all workers completed surveys at the same time intervals as the intervention sites. Workers were introduced to the study at an initial toolbox talk or at new worker orientation. They were also asked to complete surveys, at the same time intervals as the intervention sites. For the data collection periods, a banner with the program's logo was posted on the control group sites, similar to the intervention sites. No other information was provided, and no other activities were completed on control sites.
