Can I skip work without telling anyone?
Why would you skip work without telling anyone?
I have a bad case of wicker disease, I'm going to die if I go to the work
If you feel something is affecting your life and work performance then you should consider taking sometime to yourself and practice some self-care. However, if you don't give proper notice, it is possible for your employer to fire you.
Maybe I don't give a shit how they feel about my sickness? I could die.
I understand, and if you are really feeling sick then it is fine to take a few sick days off. Just call them up and tell them that you need to step away and explain your disease-- they would by law have to allow you to stay home.
