“Included and excluded services.” If the services performed during one-half or more of any pay period by an individual for an employing unit constitute employment, all the services of such individual for such period shall be deemed to be employment; but if the services performed during more than one-half of any such pay period by an individual for an employing unit do not constitute employment, then none of the services of such individual for such period shall be deemed to be employment. As used in this Section the term “pay period” means a period (of not more than thirty-one consecutive days) for which a payment of remuneration is ordinarily made to an individual in the employ of an employing unit. This Section shall not be applicable with respect to services performed in a pay period by an individual in the employ of an employing unit where any of such service is excepted by Section 222.
