Attendance policy

Question lang po. Yung company na pinapasukan ko (bpo) previously had an attendance policy where in employees were given a certain number of points tapos pag nag absent or ma late ka babawasan yung points na pinag simulan mo. Now, hindi yun na bantayan ng management so yung iba nag negative na pero wala pa ding kaso. Implemented yung policy na yun sinula nung nag start yung company. Ngayon dahil malala na yung issue, pinaluran nila yung policy. Ang problema hindi lahat ng empleyado ay nag start sa pareparehong sanction... Yung mga negative yung points binigyan ng final written warning agad tapos isng absent eh 2 days na agad. Question, legal po ba yung ganong changes sa policy? Given na hindi naman fault ng empleyado n napabayaan nila ung lumang policy. Note: pinirmahan ko ung new policy. Thanks
