If the basic salary is less than Rs 6,500, anyway he will be covered both by EPF and ESI. Whereas if we fix a consolidated salary of Rs 10,000 (at the time an employee joins), then he will be excluded from PF but will be covered by ESI. For ESI exemption, his salary should be at least Rs 10,001.
Now, just to avoid EPF, if you fix the salary at Rs 10,000 or Rs 10,001 to avoid ESI as well, suppose if, by notification, the government revises the salary limit for coverage to Rs 12,000 or something higher than Rs 10,000, you will have to give coverage then. Again, if you fix the salary (consolidated) at Rs 10,000, then his leave encashment and other entitlement in case of layoff, retrenchment, and even gratuity will be calculated on this consolidated amount only. We cannot put a full stop on bonus eligibility, which may also be raised at any time. Therefore, I feel it is better to go along with such social security measures.
