My Sick Leave I'm not sure about you, but us mere mortals get sick now and again. So if at any stage in your career with MD Health you are unwell or unable to perform your duties due to a medical condition, it's a simple matter of going to your GP, get yourself checked out to make sure all is ok, get a medical certificate and still have the ability to take time off due to illness and still be paid. Unlike other private practices on commission-based pay, if you're not around to see patients, it's a guarantee that your pay check is not coming in the mail either! So whatever you do under this pay system, make sure you have super hero powers not to get sick. Good luck.
