Tony Arbour, London Assembly Member and GLA Conservatives spokesman on economic development is today calling for a minimum wage holiday for London’s small and micro-businesses involving an exemption of up to six months.
The national minimum wage will be increased by 1.8% in October 2013.
This is 50 per cent higher than average wage growth and the decision has been criticised by many business groups.
Tony Arbour said,
“A time of high unemployment is not the right time to be pricing out those at the margins of the labour market.
I think it is important to now consider the idea of a minimum wage holiday for micro businesses and start up companies who employ fewer than 10 members of staff. This will encourage these small enterprises to take on new workers.”
