Issues with management

It seems they are  resorting to unfair laborpractice and  subjecting you to explointation taking advantage of your  goodness. Talk to your MD regarding  asking you to come and work even on National holiays etc and whether they would  allow you  to have fun on Holidays. If your MD refuses to consider your point of view and insist oin  your working on  even on nationa Holidays . Also if you have call center employees union you can take their support. If you have any employee grievance cell you can contact them and tell your grievance. If nothing works then give a Legal notice to your Management. regarding all this and if they don't give a reply or   fails to give satisfactory reply you resign from the job.  and there are plenty of call centre jobs available in Job markets. You can join in another orgnization where they consider you as a human being and allows  you to relax on national holidays from work pressure..If you appreciate this answer please click the thank you buton on this forum..

If you can not cure, endure and quit at appropriate time.  Working without job satisfaction is bad for health and particularly at Call centers.
