“It is the duty of any party wishing to join the Communist International to
conduct systematic and unflagging communist work in the trade unions,
co-operative societies and other mass workers’ organisations. Communist cells
should be formed in the trade unions, and, by their sustained and unflagging
work, win the unions over to the communist cause. In every phase of their
day-by-day activity these cells must unmask the treachery of the
social-patriots and the vacillation of the ‘Centrists’.”
