Do contributions have to continue once a member of staff has been put into a pension scheme, but their earnings drop below the earnings threshold for automatic enrolment?

If a member of staff has been enrolled into a pension scheme and their earnings drop below £192 a week (£833 a month) during a pay period but remain above £120 a week (£520 a month) you will still need to pay contributions. If they earn below this amount you need to check with the scheme regarding payment of contributions.
