Public transport is responsible for delaying employees on their journey to work at least once a week, new research has revealed.
According to Abbey, workers are late for work by 36 minutes around once a week due to unreliable public transport.
Managing director of Abbey's Business Banking Ian Wilson noted that such problems can come at a great cost to employers.
"The impact on our working day is often overlooked," he said.
Mr Wilson added: "The smaller the business the greater the burden of staff lateness, so the onus really is on the individual to build in enough time not to leave colleagues and bosses in the lurch."
The research also found that poor public transport also meant 500,000 workers cannot get to work at least once each month.
Yesterday, Mick Hegarty from BT Business noted that there are several benefits from home working - one of which is the lack of commuting.
