Construction worker in the context of "Cornerstone"

The working class refers to a group of people in a social hierarchy, typically defined by earning wages or salaries through their ability to work. Members of the working class rely primarily upon earnings from wage labour. Most common definitions of "working class" in use in the United States limit its membership to workers who hold blue-collar and pink-collar jobs, or whose income is insufficiently high to place them in the middle class, or both. However, socialists define "working class" to include all workers who fall into the category of requiring income from wage labour to subsist; thus, this definition can include almost all of the working population of industrialized economies.

A blue-collar worker is a person who performs manual labor or skilled trades. Blue-collar work may involve skilled or unskilled labor. The type of work may involve manufacturing, warehousing, mining, carpentry, electrical work, custodial work, agriculture, logging, landscaping, food processing, waste collection and disposal, construction, shipping, and many other types of physical work. Blue-collar work often involves something being physically built or maintained. In social status, blue-collar workers generally belong to the working class.

In contrast, the white-collar worker typically performs work in an office environment and may involve sitting at a computer or desk. A third type of work is a service worker (pink collar) whose labor is related to customer interaction, entertainment, sales or other service-oriented work — particularly those service jobs that have been traditionally considered to be women's work, such as secretaries, nurses, teachers, early childhood educators, florists, etc. Many occupations blend blue, white, or pink-collar work and are often paid hourly wage-labor, although some professionals may be paid by the project or salaried. There are a wide range of payscales for such work depending upon field of specialty and experience.

Gerontechnology, also called gerotechnology is an inter- and multidisciplinary academic as well as a professional field that combines various disciplines of gerontology and technology. Sustainability of an aging society depends on our effectiveness in creating technological environments, including assistive technology and inclusive design, for innovative and independent living and social participation of older adults in any state of health, comfort as well as safety. In short, gerontechnology concerns matching technological environments to health, housing, mobility, communication, leisure, work and also the personality/individual dispositions of older people. Gerontechnology is most frequently identified as a subset of HealthTech and is—since the 2010s—more commonly referred to as AgeTech or Agetech in Europe and the United States. Research outcomes form the basis for designers, builders, engineers, manufacturers, and those in the health professions (nursing, medicine, gerontology, geriatrics, environmental psychology, developmental psychology, etc.), to provide an optimum living environment for the widest range of ages.

Falling is the action of a person or animal losing stability and ending up in a lower position, often on the ground. It is the second-leading cause of accidental death worldwide and a major cause of personal injury, especially for the elderly. Falls in older adults are a major class of preventable injuries. Construction workers, electricians, miners, and painters are occupations with high rates of fall injuries.

Long-term exercise appears to decrease the rate of falls in older people. About 226 million cases of significant accidental falls occurred in 2015. These resulted in 527,000 deaths.
