From THE CHRISTIAN SCIENCE MONITOR:

62-year-old British grandpa, Paul Marshallsea, was filmed yanking a six foot long shark away from waders at Caloundra beach near Brisbane in January. Many called him a hero. But his intervention also caught the eye of his employer, the Pant and Dowlais Boys & Girls Club,who promptly sacked him. Marshallsea had been on leave since April after saying he was suffering from work-related stress.

Oh, what a bummer! And to be fair, Mr Marshallsea's doctor had told him to go on holiday as he thought it might help him recover. Obviously there are sharks all over the world.
