No, once a member crosses the wage ceiling of Rs. 21,000, he/she will be outside the purview of ESI. However, if he/she crosses the wage ceiling of Rs. 21,000 during the contribution periods (April to September & October to March), he/she will continue to be covered under ESI till the end of the respective contribution period. After the end of the contribution period, he/she will be out of ESI coverage. Thereafter, he/she cannot be a member of ESI.
