It has been obvious for the last year that, despite any comments otherwise, the government doesn't really care how much inconvenience is suffered by passengers. In such circumstances, the unions simply do not have any "strength". Even if they continue strikes for years, they will not get any settlement they consider acceptable from this government -- and they would be unwise to think they might get something much better if we get a Labour government in 2024 or 2029 (the national money box is likely to be almost empty for years to come).
