Playing favorites

In my workplace I have noticed something about the management there. They play favorites. With some employees they are really strict with. One of my coworkers got told that she exceeded the amount of absences allowed in a 6 month period (which is five) and if she didn’t stop she was going to be fired. Now I have had more than 5 absences in a 6 month period and they have said nothing to me. Actually they approved all of them but 2. My coworker also said that when she requests time off, she always gets denied. They have approved 2 of my requests without question. So my coworker said my workplace plays favorites and it is true. I should be happy that I am one of their favorites, and I kind of am. But on the other hand I feel kind of guilty that I am one of their favorites, because I feel bad for those who aren’t. I don’t know what I did to get on their good side. My boss has already said that I am a good asset to this company. I don’t know why that makes me feel kind of bad. Some of my coworkers really try their best and show up far more than I do..they should be the ones that are their favorites, you know? I don’t feel like I deserve that classification. But maybe I am being too hard on myself. When I come to work, I do my very best. Maybe they like the way I do things. But, still, I wish my workplace didn’t play favorites. I wish everyone was treated equally. But I guess that’s not the way the world goes.
