Statutory compliance of ESI due to dual employment issues - part-time night shift operator in another company

A person working in a company his salary is above 22000 so esi is not covered. That same person joined on 1st Dec 2020 as part-time night shift operator in another company with 9k salary did he is eligible for use. In the new night-shift job, they will bank transfer the salary in the same bank account which is the same bank account that is working full time. I asked them for cash they denied it. Need suggestions.

Esic coverage is applicable to employees earning less than 21k salary.
Esic uses only one employee one IP policy so in this case he will only be able to get registered at one employer only.

Dear Mahesh,
The employee can be insured under ESI where he is drawing salary of Rs 9,000/- because the ESI Act or any other Labour Law does not differentiate between a full timer or a part timer.
