Hmm let me have a quick stab at it...
According to my attached diagram, an employee has exactly one schedule, and any particular schedule can only belong to exactly one employee.
A schedule consists of many workdays (like Mon 9-5, Tues 5-10) but each specific workday record belongs to only 1 schedule (although you can obviously add many of the same days/hours to different schedules)
This would convert to:
EMPLOYEE (employee_id, employee_name, employee_address...)
SCHEDULE (schedule_id, employee_id, schedule_datecreated, schedule_isactive...)
WORKDAY (workday_id, schedule_id, workday_startdate, workday_enddate, workday_complete...)
...where underlined attributes are primary keys and italics are foreign keys and workday_startdate and workday_enddate could be attributes of type "DATETIME" (stored like: '2006-03-01 09:00:00') with a few other attributes i added off the top of my head for things like making a sched inactive and marking whether a workday for a particular employee's sched was completed
