I worked for Whole Foods for a while too, and can vouch that even prior to the Amazon acquisition this is how they rolled. I was hired during a hiring freeze when they weren't hiring new outside FT people. My team leader needed me full time, so we learned that, internally at least, the constraints on PT/FT status weren't the weekly hours worked but the average weekly hours during a fiscal period. This led to a situation where I worked a couple 25-30 hour weeks, then went down to 8-16 other weeks.
