Theme of Interest
Regardless of the organisation or industry, having a safe work environment is very important. Any injury could cause a major issue to the victim’s family, co-workers or the organisation itself. Other than the mental and physical suffering, the financial burden could be placed on other family members. For the organisation, having a safe environment would lessen unnecessary costs. If an employee is injured, the organisation’s productivity will decline. Other co-workers' workload will increase to cover for the victim. Safety also improves the quality of work produced as employees would be focusing on their work than their safety. Therefore, the following analysis would be to find out the factors that contribute to workplace injuries by using the dataset provided, Workplace Injuries Data 2014. So that related organisations or industries could keep in mind to reduce the number of workplace injuries occurred.
