I get a full days pay for doing half a day or more, check with your company how theirs work. Make sure to let accounts know you’ve worked in case your manager forgets to.
KIT days can only be taken during maternity leave and they should be full pay for however many hours of KIT you do. Eg if you go into work for 3 hours you will get ur full hourly rate for the 3 hours your r there. This still applies if you are paid on a salary they will just break it down to hourly pay and pay u for every hour that you do a KIT, but yes unfortunately they are apart of the maternity policy and there for only count during maternity leave
Each company policy is different so I would check with them. My company pay me full pay for KIT days.
