All the issues as you have stated are strong grounds which should be taken into consideration while taking a decision upon your application for leave by the authorities.

Your previous medical condition and restriction imposed. File a medical certificate by a certified board of physicians in case the authorities want any further proof.

2) pregnant women are generally given exemption from election duty

Dear Madam,

No, this is absolutely against the law. In fact, the law states that from 10 weeks before your due date, you do not have to do arduous work, stand for long hours or be asked to do any other work that may cause physical problems.

Mothers of small children and pregnant employees would be exempted from the election duty.

District electoral officer Siddharth Komal Pardeshi assured a delegation of woman employees, who have been deployed in the election duty, led by Chhattisgarh Rajya Karmachari Sangh state president Virendra Namdev and state general secretary Puran Singh Patel, that if poll duty has been given to any woman having a child of up to 9 months and pregnant woman employee, would immediately be relieved from the duty, on getting application from such employee. Because, such instruction has been given by the election commission.

If any employee, the marriage of his/her children were scheduled to be solemnized during the election period, on getting application, they would also be relieved from the election duty. In a memorandum submitted to the district electoral officer, the delegation urged to cancel the election duty of the women employees working in the Raipur Municipal Corporation area, who have been given duty at Aarang, Abhanpur, Dharseenva and Balodabazar district and looking to their physical and mental problems, they should be given duty in Raipur Rural, North, South West assembly constituencies.

They may initiate a departmental action against you in case you fail to join your election duty.

Let the concerned competent Authority taken an action on your application seeking exemption from joining these duties. In case the Authority just sits over your application without seeking any decision thereon, approach the High Court. 

See the duty need to cancelled before hand, in case duty is not cancelled then you have to attend same as non attendance can lead to issue and departmental enquiry if RO fails to cancel the duty then in that case approach the higher official.

Dear Client,

You have justify reason to seek exemption from election duty followed by past medical accidents, submit the same with your application,  still not accepted, definite relief from High Court.

You can refuse, motherhood is fundamental right of women. No service Regulations can stand in the way of a woman for claiming protection of her fundamental right of dignity as a mother

Dear Sir,

You may file representation before your higher authorities and concerned Election Officer in the meanwhile approach the Service Tribunal or High Court to get immediate relief on the basis of your medical grounds and family history.

Your medical certificate is the biggest defence for your your health condition so rely on the said certificate firmly
