I expect that's exactly the kind of thing that will end up happening. Obviously not every operator or depot is in the same boat, but for those with lots of spare turns it is almost farcical to still pay people overtime to come in on Sundays.Where Sunday is currently outside of the working week for train crew, bringing it inside would result in increased staffing requirements. So if they're looking to reduce staffing numbers, I guess they could do so by bringing Sunday in but not increasing establishment numbers, meaning redundancy wouldn't be required.
