The Speaker’s Committee for the Independent Parliamentary Standards Authority (SCIPSA) is not responsible for creating HR policies for MPs’ staff. Its remit is to consider candidates proposed by the Speaker for the posts of Chair and members of the Authority, following fair and open competition, and to approve IPSA's annual estimate of resources.
MPs are the legal employers of their staff. It is for them to use their discretion to provide their staff with caring leave. The Independent Parliamentary Standards Authority provides template contracts for MPs to use with their staff. These allow for up to five days at full pay for time off work to deal with unforeseen circumstances and emergencies involving a dependant.
