Working full-time is defined in the United State by 40 or more hours within a given week. The 40 hours is accumulated over a set number of days, usually five, with five 8-hour shifts. However, in some professions the 40 hours could be accumulated over a lesser or greater number of days.
Depends on the job and where you're located. No time off would be brutal though. Usually just for the health and sanity of workers they arrange days off in the mix. But American labor laws in particular are total **** - it would not be out of the realm of possibility for a company to schedule someone 365 days a year, and in many states there aren't even mandatory vacation days. A lot of this is dependent on what you negotiate - and the employer has the upper hand since in "at will" employment states, they can fire you for whatever reason they prefer.
Ah a fast food place, they are on another planet. I had a 10 hour contract with burger king and that was supposed to be full time. They gave everyone the same contract, they regarded part timers as those who limited their availability because of college or whatever, but no one was promised more than the 10 hours.
5 days a week, 7 to 8 hours a day is common, but some jobs work 4 ten-hour days or 3 twelve hour shifts.
