All along till date throughout the career we have always suggested that the issues whatsoever be resolved within the company, by dialogue, gentle representation, application of rapport, negotiation, goodwill, persuasion, persistence, reasoning , citing rules, policies etc, thru union, redressal mechanism.
These usually suffice. All of us who have worked in line management, HR, personnel, marketing, sales, training and development, brand management, IR . etc and have handled the real life situations shall agree.
However if these do not fetch any relief then other avenues may be explored, including legal recourse.
It is felt that the circular posted above in thread (iv) and other points do not cover the grievance of the employee.
The charge leveled is unfair means which the querist has denied. The termination is caused based on suspicion. The quesrist applied for copies of documents which were denied.From this thread and other posts it is implied that the bank has terminated large number of employees based on charge of suspicion.
Since there are many employees it can be believed that many of the employees might have approached the union/association or union/association might have come forward for the rescue of the employees.
Since the establishment is based pan India and the union/association is also spread pan India all employees must have heard from union/association. It is sheer guess that in the absence of a tangible and prudent outcome aggrieved employees must have knocked at the doors of courts of law.
Although learned High court has granted relief to the employee it is the bank which has approached Supreme Court.
However taking a cue from your post, if there is any scope of rapprochement and relief to the employees, suffering from the decision of executive that may be shared in this thread. It shall help the larger interest of employees and citizens, and it shall also restore the faith of employees in establishment and redressal mechanisms.
