I almost agree with bigGlitterstar, or at least have a very tough and -unexpected- and complete audit of their operations, if you think the Florida operations are pulling the same load as your other geographic area/locations, and that they living up to your expectations and their potential.
I don't usually suggest that the baby be tossed with the bath water, and you may have some really hard workers that deserve and are not getting the thanks their effort is worth to your company.
