Do you know who'll be teaching your children when they arrive at school each morning?
A Good Morning Britain investigation has uncovered the use of an ever increasing number of supply teachers in England with private agencies earning hundred of millions of pounds a year.
Whistleblowers have revealed to us how profit-driven agencies encourage them to lie about their experience and pay them as little as £10 pounds per hour.
We've also exposed that schools in England have been paying £1.26 billion a year on supply teachers, at the same time as warning they may have to shorten school hours due to shrinking budgets.
Watch the video above to find out what some anonymous supply teachers have to say on the matter - plus we speak to a former supply teacher who now runs her own agency and a headteacher who has strong feelings about the issue.
