<human>: I have worked for a company for about 6 years now. It is a small company. Less that five people. When I first started I was only given 3 vacation days a year and no sick leave. Eventually it became 5 then 7 and now its 10 vacation days with 3 sick days. Which I am perfectly fine with and have no problem with it. My boss sent us an email telling us what days we had off including 10 vacation days and 3 sick days. He has never been clear on what constitutes a sick day. Every time I go to talk about the sick days he gets upset and just doesn't answer. Well yesterday when I try to take a sick day due to dental work and the possibility of needing to go back in a week or two I all of the sudden have 2 days of sick leave and not 3. He is doing this because other companies don't even have sick days. Can he do this?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Boss sent me an email saying I have 3 sick days and now he has changed it to 2 because I was trying to figure out how it worked.
