OK, as a GSA at both my stores I did far more. Not as much as a GSTL, and I'll be the first to say so. But I open/close on my own, and am expected to be the first line of defense at Guest Services (and de-escalate a lot of situations without having to involve higher-ups). I didn't just roll over if I thought something was fraudulent or if something violated Target's policies. (It was my higher-ups who did that.)
That said, I know ASANTS, and I also saw more than a couple of people who became GSA and turned it into an excuse not to do anything.
We have plenty of people who are up to the challenge. We also have plenty who aren't. It's that second group that has me worried.
Our old S&E Leader also let people cherry-pick their availability, and most of the qualified folks aren't available on evenings or weekends. Because of that, from a purely selfish point of view, I don't want to have to close all the time until everyone gets up to speed.
