Dear Dr. Bijoy,
First examine/ analyze, why they are refusing to acknowledge, % of refusal, is it really a Circular on general behavior and is the circular so requires acknowledgement.
Accordingly you have to react.
If you feel that the management is right, it is better convince the employees for acknowledging the circular
or
You can convince the management that the circular has served the purpose ( As I understand, the circulars has been read by everybody, and pestering further is unwarranted.
Or as of a last resort;
1. Refusing to acknowledge an Office order or communication can be treated as misconduct as per S. O. s/Code of Conduct, disciplinary proceedings can be initiated.
Or/ and
2. If any Union is behind the episode, you can call and negotiate them for a smooth work culture and atmosphere.
In case of failure, you can take the shelter under ID Act for complaining for the union’s unfair labour practices.
As HR Personnel, we are supposed to respect the sentiments of Employees also. Off course, maintaining cordial relations is two-way traffic.
Finally, in any Organization, discipline matters more than the sentiments.
