Pesach

Passover is coming. I know the fist two and last two days we are not to work etc. My question is during the intermediary days. Is it better to not work on those days at all? I am a recruiter by profession and work on the computer all day and phone. Also drive to the office and sometimes write. Should I not work at all during the intermediary (middle) days of Passover or should I request to work remote during the middle days so I can still work but I don't drive? Thank you.

If you own commercially processed food that is not certified as kosher for Passover, but contains no actual chametz in the listed ingredients, are you required to sell it with your chametz?
