The issue came to light when Mian Mir Hospital, run by the City District Government Lahore, Medical Superintendent Dr Muhammad Sarfraz allegedly slapped a Christian paramedical staffer for not attending the assembly, the Express Tribune reported.
Following the incident, all paramedical staff protested against the superintendent and other hospital administration by shutting down all functions of the medical facility.
"This act of the MS is a violation of the Constitution of Pakistan," a Christian paramedical staffer, Marshal, was quoted as saying by the paper.
"It is professional workplace; I don't know why the administration is forcing our Christian brothers to do this. This is totally unacceptable," said another staff Fahad Ahmed.
Meanwhile, City District Government Lahore Health CEO Dr Muhammad Saeed said a high-level committee had been formed to look into the matter and a strict departmental inquiry would be initiated against anyone found guilty.
The hospital was named after Sufi saint Hazrat Mian Mir who rose to prominence during the time of Mughal emperor Jehangir. The saint himself was a big proponent of interfaith harmony.
