Factors that can adversely affect MGNREGS workers' employment in Odisha include:

• Natural calamities such as floods and droughts;
• Lack of proper implementation and monitoring mechanisms;
• Non-availability of funds or delay in fund release;
• Lack of awareness among workers about their entitlements;
• Limited participation of women and marginalized communities;
• Difficulties in accessing work sites due to poor connectivity and inadequate transportation facilities.

There are several causes for job card-Aadhaar mismatch that result in the absence of work opportunities for MGNREGS workers:

• Outdated or incorrect information on the job cards, which can happen due to administrative errors or lack of awareness among workers;
• Lack of coordination between the MGNREGS and Aadhaar databases, leading to discrepancies in the information;
• Non-availability or incorrect information on Aadhaar cards, which can be due to technical issues or lack of awareness among workers;
• Identity theft or forgery, where someone else uses the worker's Aadhaar details to claim work;
• Delays in verification and authentication processes, which can result in missed opportunities for work.

To address these issues, it is important to have a robust monitoring and grievance redressal system that can identify and resolve issues quickly. In addition, regular awareness campaigns and capacity building programs can help workers understand their entitlements and avoid job card-Aadhaar mismatches.
