In regards of Techs moving from company to company, with my company we give you one chance to come back and not everyone get's that. We're very selective. Depends on if you've burned your bridge. Screw us once, shame on you. Screw us twice, shame on us! Also, just because someone has experience from a competitor doesn't mean they are a good hire. You must do your due dilligence. I usually talk to their former customers. If the customer likes and respects them, that tells a lot. Even after all of that, they still have to pass our entry level test and I've seen many very good mechanics that could not do this.
