Aditi,
I adhere to Manjay comments, further i would like to add more,
1. Dont show negligence in their queries or requests, sort it out at the earliest and show them they are your priority.
2. On DOJ itself, impress the employee towards your company by offering the necessaries in time.
3. How about your manufacturing unit location, whether it is feasible for employees to reach your unit within reasonable time? if not so arrange for the company transportation.
4. Offer some healthy snacks for free (like boiled egg, milk, banana...)
5. Effect reasonable rates in canteen.
6. Ensure that there should not be no partiality in giving OT hours to the employees.
7. Offer some additional benefits who are working for long OT hours (Such as transportation, free food of their interest, tea / coffee, right payment)
8. If your workmen are under contractor, you should ensure about the facilities offered has been reached the end user.
These are some basics to be followed.
Regards,
Sridharan J
