Just checked the team agreement to see who's on call tomorrow (under CG rules, we're not allowed a rota so we have an agreement amongst the team as to who will assume IRT cover on a particular day, and then the boss writes it down in Excel format for easy reference. But, its definitely NOT a rota).
So, the team agreement shows Messrs Craker and Brown on IRT for the night of 31st November.
Hang on a sec......31st November?
