The metro witnessed yet another unique protest movement & march of College PTTs on Friday, 18th Dec, '15 when PTTs from all over the state walked in a procession from Subodh Mulluick Squire to Esplanade, stopping at all major street crossings to perform symbolic protest rituals addressed to the Education Minister of the State. Chanting of mock hymns & mimicry in protest of the Govt's paltry beggar's rise of teachers' salary by 25% a few days back, were on the lips of the marchers. Mrs Elora Biswas demanded pay scale like full time teachers for all PTTs, along with other benefits.
