Warning letters

How come I received two warning letters within a week? The point is I only work two days a week.

Every week, I work on Wednesdays and Sundays because there are horse racing on these two day only. However, this week had something different. I did not realize that there was horse racing on the Saturday instead of Sunday. I met my friend on Saturday. When she first saw me, she asked “Why are you here? I saw horse racing on the TV.” I quickly checked my schedule and… OH MY GOD. I should be at work. Therefore, I receive my first warning letter because I forgot to go to work.

Today, I phoned to the Jockey Club asking for my new working timetable this month. Unfortunately, they told me to go to work tonight. Suddenly been told to work. I said I was not going to work this night, then she kept saying "You will receive warning letter." for several times. "You will receive warning letter." "You will receive warning letter." "You will receive warning letter." "You will receive warning letter." OKAY. I know. I know I will receive warning letter.

In fact, my working schedule supposes to be on Wednesdays, Saturdays and Sundays only. How could they assign me to work on the day that I do not need to? They said I would need to work if the Jockey Club makes some sudden changes on the working timetable. What the hell! You know, the sudden change is not in the range of my working schedule. I chose this schedule just because I do not have time to work on the other day. What is the point of choosing this schedule if I still have to work on the other day? Anyway, I receive another warning letter again three days after the first warning letter.
