answer: #Person1# and #Person2# try to make up for staff shortage. #Person2# suggests letting Tommy stand in.
documents: #Person1#: John hasn't turned up and Stefan is ill. Do we have anyone on stand-by?
  #Person2#: I'm afraid not, we're very short-staffed at the moment. Can you ask the shift supervisor to ask one of his team to do some overtime? Perhaps Tommy can stand in for an hour or two until we find a replacement.
