Organised by the International Socialists, later the Socialist Workers Party, the Right to Work marches started in 1972. Groups staged a rolling series of organised marches across Britain that sometimes concluded with a big rally.
SDS manager HN307 Trevor Butler held up two instances of SDS assistance as examples of effective policing of the 1980 and 1981 Right to Work marches. As with most demonstrations that the IS/SWP organised, the Right to Work marches had a well-publicised schedule, so it is unclear what relevant information the SDS could have added to these publicly advertised events.
The only recorded instance of public disorder on these events occurred in 1976 when a Right to Work march passed through Hendon and was attacked by the police.
