Human and ergonomic factors are of key importance in the workers' performance in any task or activity sector. Its effects are multiple and have impact on different sectors such as: productivity, work safety conditions or workers' health and welfare, among others. As a cross context with a high impact on individuals, families and societies, it is pertinent to develop studies to identify problems and, in the future, delimit and eliminate them. Note that the size of the problem is highlighted globally, by the World Health Organization (WHO) that relates in their site: “Injuries continue to kill 5 million people each year” (WHO, Global Health Observatory (GHO) data) and “Work-related health problems result in an economic loss of 4–6% of GDP for most countries” (WHO, Fact sheet N°389, April 2014). This fact led to the proposal of a special issue addressing themes so diverse such as mental workload, mental fatigue, workaholic, work-family conflict, psychosocial risks, and workplace incivility, all constituent portions of the global problem: human factors influencing workplace health and safety. This special issue aims to highlight some of the aspects and innovative approaches to the subject, contributing to their development and deepening.
