There are some junior staff in my organization that are not interested in the pension scheme as their salary is just barely sufficient, is there a provision of the pension act to cover this?
Can they be termed contract staff?
Please who can help.

All employees are mandated to contribute pension towards their retirement.
Majority of the people we tag as contract staff working in Nigeria banks, are employees of other companies seconded to the banks.
If your letter of employment says you are an employee of ABC limited, and ABC limited sends you to ZZZ bank to go and work as a teller, ABC limited is mandated to deduct and remit your pension.
If you were specifically employed by ZZZ limited and your letter of employment says you are a contract staff employed for a particular purpose and period without benefits, then you wont need to contribute pension.
