An employee shall be entitled, at the option of the employee, to take this leave on a reduced leave schedule, except that:
The employee shall make a reasonable effort to schedule reduced leave so as not to disrupt unduly the operations of the employer and the employee shall provide the employer with prior notice of the care, medical treatment, or continuing supervision by a health care provider necessary due to a serious health condition of a family member, in a manner which is reasonable and practicable.
