This article[1] has a bit more detail. It mentions:
> The maximum work hours for workers in Karnataka industries will be 12 hours in a day but capped at the same 48-hour work week. This means workers can put in 4-day or 5-day work weeks while more flexibility is available for the management of daily production lines.
> Finally, women will now be allowed to work night shifts – from 7pm to 6am.
