Last year saw mass protests by public sector workers over their pensions - with more days lost to strike action in the November demonstrations than any time since the early 1980s.

David Thompson spoke to Conservative MP Dominic Raab and the former union leader and cabinet member Alan Johnson on the state of industrial relations and calls for anti-strike laws.
