Overburdened. Overworked. Overweight. That’s the Mumbai Police personnel in a nutshell. But this, the department hopes, will soon be a thing of the past, if their fitness plan steered by the shift timings of corporate work culture, goes as planned. Beginning November 1, constables, assistant inspectors and sub-inspectors at JJ Marg police station in Byculla will have to clock in only seven-hour shifts, down from 12 hours (or more, if needed).
