Continuing on from an earlier Q&A

... how do we know how long to continue to pay SMP, i.e what if the employee finds employment elsewhere before the end of her maternity leave entitlement (she commenced maternity leave on 7 Jan)? She will no longer be an employee with effect from 31 March so will not have communication with her.

... Do we have to communicate anything to the Inland Revenue, we don't want to be claiming back SMBC that we have paid to the employee when the employee may no longer entitled to it.

... The other complication is that the employee had another job whilst working for us and we're not party to her conditions of employment. I have copied the following advice from one of the websites based on us being employer A:

"If you work for another employer (employer B) before the birth you can still get SMP from us (employer A). If you work after the birth for employer B and you were not working for employer B in the 15th week before your baby was due, your SMP from us will stop on the Saturday before you start work for employer B. However, if you worked for employer B in the 15th week before your baby was due, you may work for employer B without affecting your SMP from employer A."

I believe she was working for Employer B in the 15th week before the baby was due and I believe she may go back to Employer B before her materity entitlement expires. Do I need to ask her for evidence of whether she worked for Employer B in the 15th week in order to determine whether we continue to pay her if she goes back to them? And how would I even know if she goes back to work for them?

Sorry this is so complicated and many thanks.
