The late 70s were the height of specialised knowledge required to operate and maintain broadcast equipment.
They probably just scrapped through in 1968, which was still b/w 405, and slightly 'lower tech'. Into the 80s and with 1 inch VTRs etc, it became easier, illustrated by Thames and TV-am who both managed a rudimentary service
The 1968 strike service was possible because of the franchise changes, I think. It used former ATV and ABC facilities and staff in part.
A strike lasting nearly three months must have been unprecedented in UK television back then. I am amazed that the ITV management allowed it to continue for as along as they did.
They were losing millions of pounds in revenue, but even that would not get the unions and ITV to come together and agree a deal?
Why didn't the management not discuss it with the unions after say a month off air. When the autumn schedules were about to kick in September 1979, surely then they would see a deal had to be arranged?
Certain ‘players’ within ITV’s management wanted a long summer strike to break the unions. A huge miscalculation on their part. An earlier settlement would have saved ITV a lot of money. I didn’t enjoy being on strike for 11 weeks.
