The Committee for Slum-dweller Workers’ Rights (BSARC, Bastibasi Shromojibi Adhikar Raksha Committee) arranged some activities to commemorate May Day 2021. Among others they sing the International in Bengali.
The main points in the photos are about protecting workers rights and specifically in this case workers who are slum dwellers. They also talk about providing proper rations to all the eligible people, specifically in the context of the lockdown in India amist the pandemic. Furthermore the need for workers’ unity is emphasized.
