Hi Sai as per the S&E act they have revised the timings or shift to 9 hours. However it explicitly mentions that no employee is allowed to work for more than 9 hours a day or 48 hours per week. Total number of work hours including overtime should not exceed 10 hours a day except on the day of stock-taking and preparation of accounts.
This 9 hours includes 1 hour of breaktime (can be given in parts)
