HYDERABAD, Nov 26: More than 7,000 teachers observed black day on Wednesday in 248 government colleges of the province in protest against manhandling of ad hoc lectures by police in Karachi when they were holding a demonstration outside the CM House to press for their demand for regularisation of service.

The Sindh Professors and Lecturers Association had given the call for protest. The teachers boycotted academic and co-curricular activities, wore black armbands and held meetings to condemn police attack on peaceful protesters.

They passed resolutions, demanding action against police officers, regularisation of services of ad hoc lecturers on the pattern of Punjab, NWFP and Balochistan and appointment of 651 candidates who had passed the test for lecturers’ job.

In Umerkot, academic activities came to a halt as teachers wore black armbands, boycotted classes and hoisted black flags on college buildings to protest against their colleagues’ torture.
