Why might productivity decrease as a result of poor manual handling practices?

Productivity can decrease due to poor manual handling practices primarily because injured workers may need additional time off. When employees engage in improper lifting techniques or do not use correct posture, they increase their risk of injury, such as strains or sprains. These injuries not only require medical attention but often necessitate time away from work for recovery. This absence can significantly disrupt workflows, reduce the overall workforce capacity, and hinder project timelines, ultimately leading to lowered productivity levels.

In contrast, options related to motivation or workplace culture improving do not directly link to the influence of manual handling practices on productivity. In fact, if manual handling leads to injuries, it may negatively affect motivation and morale among remaining employees who may be taking on extra work to cover for absent colleagues. Similarly, while tasks becoming easier seems beneficial, improper handling generally makes tasks more difficult and can lead to more accidents and inefficiencies rather than improvements. Thus, the connection between workplace injuries due to poor handling practices and decreased productivity is significant and directly aligns with option B.
