If you are not family or have an "in"with management, they will fire you within a year (I saw 2 people fired within 1 yr of employment, and my entire team worked there for less than one year before we were gone)
they won't offer benefits unless you work there for 1 full year (see previous con)
They may ask you to babysit their children as they bring them to work.
their pay is less then the going rates for your position
