The solution questions:

Why are labor unions formed?
What is their purpose?
Why has membership seen a decline in recent years?

Certain industries, such as public safety, government (postal carriers) and engineers, are often represented by unions. The membership elects a Board that engages the organization’s management in negotiating hours, wages and working conditions for all members. Declines in unions, in recent years, may be attributable to increasing union dues that members must pay and the struggling economy. Workers do not want payroll deductions for dues and organizations can often find “cheaper” labor outside of union employment.
