To get SSP for the member of staff off sick, you need to ensure that the absence is marked as sickness in Moneysoft Payroll Manager, and then SSP will automatically calculate. However, if the sickness is related to a previous illness before 28/12/2022, it may not be entitled to SSP. You may need to seek advice from a HR or payroll specialist to confirm this. It is also not clear what the relevance of the amount of £1054.50 is in relation to the question.
