one of my workers violated modal standing orders(i.e escaped from work spot without proper approval from HOD's) .After that we have guided personally but no improvement so we issued show cause notice to him but, the worker rejected to accept the show cause notice and he rejected to put signature and neglected the same.Now, what kind of action i have to take against the same worker.Kindly guide me. And all others workers also not ready to give information against him. because they have union so that, we do not have any evidence against him to take action.So, in this complicated situation what i have to do?
