Inefficient public transport is leaving workers late and costing businesses money, it has been claimed.
A study by Abbey Business Banking has revealed public transport users are late at least once a week and more than half a million fail to get to work at all.
The problem is worse in the south-east where 42 per cent of workers depend on its busses, trains and tubes to get to work.
Managing director, Ian Wilson, explained the setbacks were inconvenient but "the impact on our working day is often overlooked, not to mention the cost to our employer".
The research estimated the total cost to industry was £212 million and at least 24,000 Brits miss at least one full day at work each month.
Mayor of London, Ken Livingstone, introduced the congestion charge in 2003 hoping it would reduce congestion on the roads and make travel to city offices easier.
