3. A was hired on probationary basis by XYZ Industries. Upon the expiration of the probationary period of six months, A was informed that he failed to meet the required standards to be regularized. A begged that he be given a chance to improve his performance. The company agreed and extended the latter’s probationary period for another three months. A’s performance, however, did not improve. Thus, XYZ Industries terminated his employment at the end of the extended period. A filed a complaint for illegal dismissal, claiming that he already became a regular employee after the expiration of the original six-month probationary period. Is A correct? Reason(s).
