I agree with the views of Mr. Lalit Takkar.
If you are drawing lessthan rs.15000/- per month you will be covered under ESI Act under which it is mandatory for your employer to send an accident report within 24 hrs. From yopur narration that your employer did not bother about yopur injury. you may not be covered under ESI Act.
Therefore, Employee Compensation Act, 1923 applies to you and your employer is liable to pay compensation and incurr full medical expenses. For the temporary diablement period you are entitled for 50% of your salary as compensation. After your surgey, if looss of earning capcity has resulted, appropriate compensation is payble by your employer with the deduction of already paid 50% salary called half-monthly payment which is not p[aid in your case and therefore it is irrelavant. Please approach the Employee Compensation Commissioner of the area in which your site is located and file your claim along with your mmediacl bills and medical certificates. A designated officer of the Labour Department like, Dist Labour Officer or Asst Commissioner of Labour or Dy Commissioner will normally be designated as Employee Compensation Commisioner. Please meet in person the Employee Compensation Commisioner of the area and ask for help and he would guide you. Normally, some advocates practice Employee Compensation cases whose details may also be got from the Labour Department.
You will not be entiled to salary during the period of your temporary disableemnt under the said Act.
