In my company, one has to apply for PL 15 days before, I applied for it 40 days before and one more employee also applied in same duration some 20 days before but my boss accepted his leave and not mine and when asked why, he told randomly he did sanction one and other rejected. On one more occasion he sanctioned other employee leave, i.e. PL which was applied just 1 day before. I feel that he is bias. What remedy do I have. Please guide.
