As used in section 13(a)(15) of the Act, the term casual basis, when
applied to babysitting services, shall mean employment which is
irregular or intermittent, and which is not performed by an individual
whose vocation is babysitting. Casual babysitting services may include
the performance of some household work not related to caring for the
children: Provided, however, That such work is incidental, i.e., does
not exceed 20 percent of the total hours worked on the particular
babysitting assignment.
