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.
