What is the difference between consecutive FMLA and intermittent FMLA?

Intermittent FMLA means that an eligible employee can take leave on an "on" and "off" basis (as needed). The employee can also take FMLA leave in a continuous way which means taking consecutive workdays as leave. The FMLA should begin for an eligible employee who has been absent for more than three consecutive calendar days for a qualified reason. 

Employees may take FMLA leave on a reduced leave schedule – reducing the employee’s usual weekly or daily work schedule. When leave is needed for planned medical treatment, the employee must make a reasonable effort to schedule treatment so as not to unduly disrupt the employer’s operation.
