Think a lot of it has become a personal battle between Jim Ratcliffe/Ineos and the workforce there.
Unite never really got over having their arse handed to them a decade ago and have spent the last ten years picking fights, some justified, some not, some official, some not.
Ratcliffe was quite honest for years that he didn’t think it was worth the hassle and was planning an exit, but found it difficult to unload.
Whether it should be nationalised is another matter entirely, lots of factors to take into account such as short term energy security and long term environmental strategies.
Plus the cost of running it as a deficit is huge, not entirely sure the country should pay for a failed/unviable business.
The thing is though that Falkirk is well placed for access to Glasgow/Edinburgh so there are alternative employment opportunities, it’s not the same situation as mining villages that are cut off and relied on one industry.
