This is the sub-section of the NES that could require you to produce a medical certificate for one day's sick leave. In reality, a certificate is generally not required for this period of time, unless specifically stated in the employer's policies or procedures.t used to be that if you were off sick for one day, that you did not need a doctors note for a single days absence, however under the new Fair Work scheme (not a union member) all leave (such as sick leave, carers leave, compassionate leave etc) is lumped under the banner of personal leave and it says:
Dehydration is a common cause of reduced GFR which is caused by decreased fluid intake, decreased thirst, diuretics and diarrhea, etc. This condition can reduce the total blood volume in body, thus reducing renal perfusion. * CKD. CKD is the leading cause of reduced GFR.
