i would develop put-together products and have classes where they can be assembled under trained supervision. you make money on the kits, the tools, and the classes.
i would let their managers manage, and get rid of some who cannot or will not.
i would have my district supervision shape up or ship out - big problem there.
i would get secret shoppers in there as well, and act upon the reports.
oh almost forgot partner with local trade schools and colleges for electronic support and training.
and support their products. i have a trunk scanner that nobody seems to be able to program
