Fastaff travel nurse assignments have guaranteed hours. You may work 36 to 60 hours per week depending on the facility you’re assigned to. Any hours over 40 allow you to earn extra income through overtime. In California, any hours worked over 8 per day are overtime. If your facility does not schedule the required hours or cancels your shift, Fastaff will pay you for the guaranteed hours regardless, so long as you were available to work.
