As extreme summer heat leads to increased absenteeism and reduced productivity, manufacturing and engineering firms like Tata Steel, Larsen & Toubro, Nayara Energy, Thermax, and Maruti Suzuki are implementing measures to protect their employees. Initiatives include providing desert coolers, air-conditioned rest areas, and AC transportation, distributing rehydration salts, conducting medical check-ups, and offering doctor consultations. Tata Steel adjusts job schedules to minimize direct sunlight exposure, while L&T extends lunch breaks for outdoor workers.
