Sir, ours is a commercial/marketng unit - supply and service.  We have sufficient manpower but dispute is about 2 offs only.

The company might be registered under (name of the state) Shops & Estbs Act and might have been granted exeption under the Act and allowed to function 24 hrs.

Inspector appointed the Act may be approached.

Okay Sir, as you wish, actually management is forcing to implement 1 off only instead of currently and past practice of 2 offs.

Thanks a lot.

For any change in service conditions advance notice of 21 days is to be given.

Don't accept.

Advance notice u/s 9 of the Industrial Dispute Act is required before bringing any change. Kindly go through it. 

Also note period of notice varies from state to state. 

In general after 48 hrs of work only one day off with pay is eligible & in case  2 days weekly offs practice is existing then as suggested by our learned friends it should with proper intimation related to the change as it is considered as a change in service conditions. 

Thank you my learned friends.  Meanwhile, our trade union leaders and myself as a local unit representative, are analyzing losses to workmen as well as officers – both so that overall after effects and repercussions in working conditions, personal & family life could be controlled/ managed properly to an extent.  Anyhow, any other way-out and suggestion/advise is most welcome.  

If there is 'Works Committee' that can take up the matter with employer.

Negotiate.

You seem to be on the right track.
