I was always under the impression that the government paid the statutory maternity pay in it's entirety but having spoken to my colleague yesterday (not my boss who deals with the finances) she indicated that the company paid some of it last time I was off on maternity?
I told her I assumed it was completely government paid (since if I wasn't coming back to the job I would still receive it and they surely couldn't be expected to pay it then...).
Does your employer contribute to the stat mat pay?
