Dear Friend
Every organisation has its own transfer policy. I think in your appointment also the said clause transfer might be there. Generally. management who are having multiple locations of business centers, will transfer their employees from one place to another depending upon the work exigencies. So management is having a right to do this one. At the same time, the reasons for such transfer should be on genuine ground and it must be free from the act of victimization on part of the employer. In your case whether the management action in transferring you to new place which is away 900 KM away from your present location is a genuine or not, we do not know.
Generally, in any company lower cadre employee such as clerks, peons, watch and ward, security gaurds will not be transferred from one place to another. Only higher cadre employees such as branch in charge, key accounts persons or HR employee will be considered for transfer from one place to another for one or the other reasons. In your case, you have to think on these lines. How, your terms with management now a days? Are you having cordial relation with your boss or supervisors? What about your performance on job? Whether you are having any active involvement in union activities?
Even if you do not know about exact reason for your transfer, then you should go and meet your HR Dept / your immediate boss and take their help or advise in getting withdrawal of transfer order issued by management by convincing them by telling your problems which you are facing now. If they consider favorably it is ok or else, the decision of management will final and if they transfer you one genuine ground on work exigency, there is no other option left for you. In such a case, either you have to report for duty at place of transfer or else quit the job if you feel it is difficult for you to go and report for duty. Under the given circumstances, you may request the management to extend time for joining duty at your place of transfer and search for another jog in your present location and tender resignation thereafter if you so wish.
But, any cost you cannot challenge the action of management if they transfer you on genuine ground. If you refuse to accept the transfer order, management may take departmental action on the grounds your refusal to accept transfer order which amounts an act of misconduct i.e insubordination as per the provisions of standing orders / service rules of company and accordingly they may terminate your services in due course
