They can opt out of your workplace pension scheme after they have been enrolled.
But if they do, they’ll lose out on your employer’s contribution to their pension, as well as the government’s contribution in the form of tax relief.
If they decide to opt out within a month of being enrolled, any payments they have made into your pension pot during this time will be refunded.
After the first month, they can still opt out at any time. But any payments made will stay in their pension pot for retirement rather than be refunded.
They can re-join your employer’s workplace pension scheme at a later date if they want to.
