I'm going to take a day of fake sick leave when I could still reasonably work
Why do you think this is ok?
I feel justified I already worked every day this month.
It is wrong to lie about being sick to get off work. People are expected to tell the truth so they don't force someone else on their off day to cover your shift.
Yeah, I agree. Fortunately I just got a raise.
Congrats on the raise. But still you need to make sure someone else can cover your shift if you want to be absent. Do you know what might happen if they find out you lied?
