You sound like you need more PA's...an A volume store should not have just one PA.
We're actually on the cusp of going to a double A/A+. My store beats supers in comp% and regularly competes in sales with our supers.
Are you able to cross-train other tm's in your department? My store has 4 PA's plus 3 or 4 tm's who are market trained.
Cross training happens when I have the time, but I'm regularly told to keep my hands off TMs that have the necessary mindset, patience and timeliness to work six pulls an hour and handle vendors, planners and task lists, because "they're necessary for (insert random workcenter, usually flow or electronics, here)" or "you don't get all the good employees".
My store has always had dry grocery, paper and pfresh under the CTL, but they recently added pets and chemicals to my "domain".
Staffing has always been an issue at my store. Our STL and ETL-Hr have been on job for about two years, at most. HR was an outside Target hire and our STL only ever worked low volume C and "D" stores. She has the mentality that CTLs are essentially extensions of the pfresh team and that pfresh team members are responsible for everything in the grocery block (dry, paper, food storage, freezers and the pfresh U), including all planners and some revisions.
Our flow TL can't control her team and their metrics are absolutely broken. They don't back stock any product, and commonly leave freight stashed away in inaccessible locations in the store where it won't be found for hours. It usually takes a team of five to six three or more hours to work just the freezer and dairy (deli and dairy temp groups) pallets.
Our ETL-Log had no control over any part of her workcenter, and is constantly brushing off any complaints about her TLs and TMs, when she isn't hovering over my shoulder telling me that everything I do is wrong.
My team is supposed to be cut somewhere in the 250 hour range, but we routinely have to make do with 180 hours or so, because flow can't control their overspending and my department "gets extra hours because you work your own produce and meat pallets". That maths out to one opener, one mid and one closer, with myself (the "CTL", though I'm not paid CTL money, since they drug their feet and purposefully delayed my promotion from PA until after the org change did away with the CTL paygrade) usually having to play one of those roles.
So my opener has to: cull, sda, process qmos, and work one pallet of meat and two pallets of produce before eight am by themselves (M-W-F), in addition to the seven thirty autofills. On top of that, if it's a planner week, begin working on the planners I've mapped, tied, dropped in the gun, set up the shelving necessary in the fixture room and printed labels for.
I just wish Spot would quit peeing on my leg and telling me it's raining. I'm almost completely burnt out after a year. We also only have two hardlines TLs (of which I'm considered one) and two softlines TLs. We have a Senior TL in hardlines also, but she only works LOD shifts and has her head up her ass because she's busy schmoozing for an ETL position.
Sorry for the walls of text.
