Usdaw (the Union of Shop, Distributive and Allied Workers):
'Usdaw is pleased to support the work of the Close the Door campaign to improve conditions for shop workers. As well as wasting money and energy, open shop doors in winter can cause great discomfort to staff who may spend all day in cold or fluctuating temperatures. Closing the door when it's cold outside makes both staff and customers more comfortable and is something all shops should be doing.'
This is very important - just how poor working conditions can be when shops leave their doors open in cold weather was highlighted by recent data from Cambridge University. A cause for shame in the UK in the 21st Century.
