I've done a lot of work at Pearson discussing improvements to our overall safety culture. I can tell you that when workers are stressed out, when they have anxiety, when they don't know their future, that has an impact on the safety culture, because their minds are not on task.
Having a longer procurement process would allow workers to fully understand what's going to happen with their jobs. I believe that aligning it with the group termination provisions of the code—16 weeks' notice—would go a long way to ensuring that workers understand who their new employer might be. That new employer would also have a long time to get to know those workers prior to the contract changing hands officially and the new employer taking over that working group.
