Savoy Department Store (SDS) adopted a policy of hiring salesladies on five-month cycles. At the end of a saleslady's five-month term, another person is hired as replacement. Salesladies attend to store customers, wear SDS uniforms, report at specified hours, and are subject to SDS workplace rules and regulations. Those who refuse the 5-month employment contract are not hired. The day after the expiration of her 5-month engagement, Lina wore her SDS white and blue uniform and reported for work but was denied entry into the store premises. Agitated, she went on a hunger strike and stationed herself in front of one of the gates of SDS. Soon thereafter, other employees whose 5-month term had also elapsed joined Lina's hunger strike. Assume that no fixed-term worker complained, yet in a routine inspection, a labor inspector of the Regional Office of the DOLE found the 5-month term policy of SDS violative of the Labor Code's security of tenure provisions and recommended to the Regional Director the issuance of a compliance order. The Regional Director adopted the recommendation and issued a compliance order. Is the compliance order valid? Explain your answer. (2008 BAR)
