… a wage rise showing an increase in the power of the trade unions leads-contrary to the precepts of classical economics-to an increase in employment. Conversely, a fall in wages showing a weakening in their bargaining power leads to a decline in employment. The weakness of trade unions in a depression manifested in permitting wage cuts contributes to the deepening of unemployment rather than to relieving it.
