Let this be a lesson to anyone working for a company:
NEVER put the company above yourself.
They will embarrass you.
Use ALL of your sick leave every year.
Take your holidays.
Don't come in and do extra, don't do projects that will not serve you personally.
Do not sacrifice your health.
Do not be the donkey.
You can sacrifice everything for years, and they can cut you at 3AM like it was nothing - "it's just business"
They don't care about you like you think they do.
