That wouldn't be the first time. They made presenters redundant before, and then when they needed cover, they were bringing in freelancers or paying overtime to other presenters. They made Milly Griffiths redundant a few years ago - and then took her back on when they realised they needed her.
I don't understand the logic in cutting the amount of presenters down to the bone - and then drafting in freelancers, who are generally more expensive than salaried presenters, to cover when they're short. It doesn't make sense to supposedly try saving money by letting a presenter go - but then paying a higher amount for a freelancer to cover. Bizarre.
