For ten years James Robertson hasn't missed a single day of work. What's even more remarkable is that Robertson walks a round trip of 21 miles a day just to get there.

For five days a week, Robertson, 56, trudges from his home in Detroit to his job at the factory where he works in Rochester Hills, Michigan.

He's walked the walk ever since his 1988 Honda Accord quit on him more than 10 years ago.

His job pays him $10.55 an hour, which he claims is not enough for him to buy his own car, but that may well change after well-wishers managed to raise almost $42,000 for him in an online campaign in just hours.

For now though, whatever the weather, Robertson is there, on the job for his 2-10pm shift.

In the city that made the motor car famous, he is without his own four-wheels and there's no decent bus service to get him to where he wants to go, either.

'I set our attendance standard by this man,' said his boss Todd Wilson to the Detroit Free Press.

Wilson is plant manager at high-end plastic moulding specialists, Schain Mold & Engineering. 'I say, if this man can get here, walking all those miles through snow and rain, well, I'll tell you, I have people in Pontiac 10 minutes away and they say they can't get here — bull! He's never missed. I've seen him come in here wringing wet,' said Wilson, 53.
