Stacey takes five teenagers to London Zoo for their first job on her ultimate work-experience challenge. If Sharif, Allina, Louis, Kieran and Louisa do well they will earn the national apprenticeship wage at the end of every day. However, if they fail to shine, they may go home empty-handed. All they have to do is spend two days working hard as a zoo keeper and impress their boss - what could possibly go wrong? The teens start off by doing two of the keepers’ regular daily tasks - feeding and cleaning out the animals - and it all has to be done thoroughly and quickly before the zoo opens to the public. They have already been set some personal goals by recruitment consultant Ricky Martin - does their behaviour on their first job come anywhere near those high standards?
