Don Don is hired as a contractual employee of CALLHELP, a call center. His contract is expressly for a term of 4 months. Don Don is hired for 3 straight contracts of 4 months each but at 2-week intervals between contracts. After the third contract ended, Don Don is told that he will no longer be given another contract because of "poor performance." Don Don files a suit for "regularization" and for illegal dismissal, claiming that he is a regular employee of CALLHELP and that he was dismissed without cause. You are the Labor Arbiter. How would you decide the case? (2015 BAR)
