London living wage campaigner Deborah Littman says paying a living wage will require a leap in thinking to accompany a monetary leap from the $13.50 an hour minimum wage to the proposed $18.40.
She says the aim is never to have the living wage legislated for, but for it to be a voluntary, grassroots campaign. The mindset shift she is talking about is getting employers around to thinking that paying $18.40 is not a burden because it costs more, but a benefit because it results in improved productivity, reduced staff turnover and absenteeism.
"Over and over again businesses tell us when they introduce the living wage they find their business does better - their staff turnover goes down and the cost of recruitment is lower."
The living wage campaign in Britain has business allies including KPMG, PricewaterhouseCoopers, Barclays Bank and HSBC.
Ms Littman says low-pay comes at a cost to society as a whole.
