Your ETL-HR sounds like she is really trying to sell you on the HRTM position. However, I recommend that you ask yourself if HR would be the right fit for you.
I enjoyed doing HR but it was definitely not an easy desk job. There were definitely its challenges. Realistically ask yourself if what I mention below sounds like something you would be interested in doing.
You will need to be able to work independently and as a team. Your team will be very small and there is a lot of work to do in a short amount of time along with constant interruptions. You may get pulled away to do non-HR stuff as well.
HR multi-tasks many different things: pay, recognition, scheduling, staffing, promotions, terminations, disciplinary action, leave of absences, ordering supplies, calling people to replace shifts, helping TMs with issues, printing reports, responding to e-mails, etc. There are long processes to each thing. For example, staffing alone already involves screening applications, playing phone tag with applicants to set up interviews, coordinating mass interviews, job offering people, running orientation, working on a pile of paperwork, and tracking every person's training. Imagine doing all of this just to have new TMs quit in less than a month. Now, your team needs to staff again.
Also, FYI, you should probably know that moving from Apparel & Accessories (a.k.a. Softlines) to Human Resources is considered a demotion because the HRTM position is now in the lowest pay grade thanks to the geniuses at HQ. According to the promotion/demotion guidelines, they are supposed to subtract $0.50 from your current pay rate for this demotion.
