PEASACAKE - when CAM gives 30 days notice, you give CAA notice immediately - I think what cladosporangium meantby "30 day grace period".
I guess you meant that CAA would NOT allow a gap of up to 30 days with no CAM.
Finally, mention of the police contract - Norfolk Police have already given notice to Sterling to terminate wef 31 March and plan to buy hours off Suffolk.
