Are verbal contracts binding when starting a new job, regarding description, duties, etc..?

During the hiring process you probably signed lots of papers you either did not or was not given time to read. Most of these employers have a sentence something like this, "......and other duties as igned." Most, if not all companies require you to sign a paper stating you will work ..."any shift needed." Ask to see all the papers you signed. Go over them and see if you signed anything to this effect. If you did, you have no recourse (but to quit) but to do the jobs igned. If I were you I would look for another job and be VERY aware of the promises made and ask for them to be put in writing.
