if procedure occurs during hours less than min guarantee (currently 149 hours) it is taken from sick leave and hours credited to your line (149/38= 3.92 hrs /day). if it occurs after you achieve the min guarantee (149) you get no sick leave hours credit but you do not lose any sick days. however if you have a medical procedure on annual leave, inform team leader immediately, any days will be credited to your next annual leave. e.g. if your medical certificate is for 7 days your next annual leave will have an extra week in it. remember, on sick leave you cannot use staff travel...hope this helps
