Apart from Job Satisfaction, how else could the Supply of Labour for a Particular Job or Industry be affected by?

-Size of the Working Population in a given Country as a whole. An Aging Population which has a Large % of Retirement may provide not enough Workers to meet the Firm's Demand -Competitiveness of Wages: Workers may pick jobs that offer the Highest Wage. This makes Firms who pay Low Wages fare Poorly -Publicising of Job Opportunities: Can be Hard to attract Workers to a Job/Industry if not properly Advertised rightly. Information Failure?
