It refers to people in the workforce who are over 65, or the standard retirement age. Grey-collar refers to the balance of employed people not classified as white or blue collar. Although grey collar is sometimes used to describe those who work beyond the age of retirement[1], its most widely accepted meaning refers to occupations that incorporate some of the elements of both Blue and White collar, or are completely different from both categories. Examples of Grey Collar industries: * Farming, fishing, forestry and other forms of agribusiness * Health care, aged care, child care and the personal service sector * Protective services and security * Food preparation and the catering industry * High-tech technicians[2]
