Dear Mr. Kumar.
As you said that, once an employee is covered under PF, he/she continue to be a member in new establisment covered under EPF. Please read
as per EPF Scheme, Para 69, (5) - Any member who withdraws the amount due to him under subparagraph (2) shall, on obtaining re-employment in a [factory or other establishment] to which the Scheme applies, be required to qualify again for the membership of the Fund and on qualifying for membership shall be treated as a fresh member thereof.
It means on his re-employment, he should required to qualify for EPF. so if his salary is more than 15000/ then he may not be EPF member in new establishment.
employer may allow to make him as PF member but in joint request in writing .
