Vantaggi
You get a free meal as a crew leader, and considering its quality food that's not so bad. I met a lot of really nice people there and the work atmosphere was somewhat laid back.
Svantaggi
I worked at a privately owned franchise, which I believe made working for Whataburger worse. The pay is horrible for the shifts you work. As an evening crew leader I was required to work Friday graveyards ending my shift at 6 am and required to be back at 2 pm for another 8 hour shift, then come in again the following day at 10am. Destroys your entire weekend. We had a ridiculous turnover rate mainly cause they will never give you a wage increase unless you beg for it. When people don't show up you end up covering for them. One week the graveyard crew leader who relieves the evening shift quit and I ended up getting stuck working double shifts for three nights. There was zero advancement opportunity after crew leader or at least that's the impression I got.
