Not every worker would be given the day off to celebrate their birthday.
But, at the grand old age of 100, Buster Martin is entitled to some special treatment from the boss.
So, instead of carrying out his duties maintaining a fleet of vans, he will today take a VIP tour of Chelsea Football Club, his favourite team.
Mr Martin - who is believed to be Britain's oldest worker - is now in his 90th year of employment.
Three years ago he quit his job on a market stall but was looking for work again within a few weeks because he had 'too much time on his hands'.
'Boredom is a big killer of men,' he said. 'I went back to work as I like to keep active. If I did not work I would become miserable so I
don't want to stop working.' Mr Martin has been taken on as a part-time mechanic and valet by Pimlico Plumbers, which is based near his home in Lambeth, South London.
He puts in three to four hours every day and says he hopes to carry on until he is 125.
He has 17 children and more than 70 grandchildren and great grandchildren.
