To shut significant parts down for an entire fortnight is clearly damaging."A spokeswoman for South West Trains, London's busiest commuter network, said peak trains were arriving at Waterloo with about 40 per cent fewer passengers than usual.Meanwhile, research has shown a record six million people are taking sick leave from work every day. Up to 166 million sick days are taken each year - 6.8 days for every employee.MORE ABOUTChambers Of CommerceEntrepreuneurshipFestive Events (including Carnivals)
