DH has no interest in ending this dispute. He is in the rather bizarre position of having no jepoardy as to the outcome whatsoever. His track record with Unite is not the best and, as such, he has a rather sadistic and self centerd interest in prolonging the dispute to cause as much harm as possible to his former employer.
As has been said before the moderate CC seem to be the victims in all of this and I hope it can be sorted out soon.
