I am returning to work on a phased basis following a period of sick leave after injuring my back. My contract allows 30 days sick leave per calendar year and my employer has paid me for the whole of January and February therefore exceeding this. I normally work 40 hours per week but will be returning initially at 3 hours per day and gradually increasing this back up to 40 hours a week. My employer has advised going forward that they intend to pay me only for the hours I work, is this the norm or is there another way to proceed? I am also unsure how this will affect my NI contributions, pension and holiday accrual so would appreciate any advice regarding this. Thank you in advance for any advice you may be able to give me.
