Immediately after the second World War a lot of left-wing activism was centred around the Spinners Hall.

However, as the cotton industry went into terminal decline, more unions and groups began to use the Club for their committee and general meetings and to organise in various ways.
In the mid-60s an anti-Vietnam war group met at the club to organise local demonstrations and coach trips to take people to the national ones.
Similarly, the Bolton committee of the Campaign for Nuclear Disarmament (CND) met informally in the club to produce and organise leaflet drops, demonstrations and trips to national marches and rallies.
