Talk to your local HR dept. However, my understanding is that the TSG groups in the districts have been de-skilled and a lot of the work outsourced. The 3 places they really need skilled people is New Jersey (main I.S. facility), Louisville (Airline and Automated Hub) and Atlanta (Corp. HQ.)
Unless you work in one of those places, you might be better off getting a job with Geek Squad at Best Buy, or a local software company. My nephew works as a TSG-type for a small software firm that writes a software package that runs vetinary clinics. It's been a good gig for him. I would be looking for smaller companies with 100-200 employees that produce and support software for niches like that. Big outfits outsource a lot of stuff overseas.
