Baggy the fact is Tesco can (and seemingly are) laying people off and then using this government scheme to employ staff who work for tesco but are paid by the tax payer.
Are you or anyone else seriously happy knowing that everytime you shop in tesco, argos (and many others) some of the people on the checkouts or stacking the shelves are doing so out of your taxes instead of that companies annual billion pound profits? Tesco etc get richer while the unemployment levels stay the same
