If the smallest ITV franchise could do it and have the will to, then the rest of ITV could.
They didn't though - Channel wasn't a management run service it was run by their normal staff
if Channel TV could put out an emergency schedule, whoever operated it, then the rest of the ITV network could do it. They had the experience from the 1968 strike. Everyone keeps saying that strike was different, but I am sorry, I still do not see how. A strike is a strike, a management run schedule in 1968 would be the same in 1979.
The reason management did not run an emergency schedule was to annoy the viewers, so to get the viewers lashing out in anger at the unions, and the management using that bad feeling from the general public to get a deal done quickly.
The management at ITV underestimated the power and willingness of the unions to remain steadfast, and not look at the press or public reaction, and carry on with their strike, and by the end of September 1979, with ITV losing millions, the management crumpled, and were dying to get some sort of schedule back on air, or a deal done.
