Good luck.
Based on your posts, you are investing too much into Target and trying to get involved in too much. You are going to experience the same burn out you say you had as a store manager but at a way lower pay check.
Trust me, the level of frustration, unhappiness, etc. you will accept is directly related to the amount on your paycheck. If you were unhappy making $20 or $30 or $40 per hour as a store manager, you will surely be more unhappy as $13 or $14 or $15 per hour as a Target team member.
Just go into work, do your job, and then leave. You can't do everything, you can't fix everything, and you can't be involved in everything.
Also, the store's performance is not your responsibility. Your shifts in your area are not going to change the sales and profit performance of your store in any meaningful way. You could zone perfectly, pull amazingly, stock incredibly, etc. and it won't move the needle in any meaningful way over an employee who barely zones, doesn't pull, and only stocks what they give them.
For example, a couple weeks ago they had me pushing books. Never did it before but merchandise is merchandise and I can follow the zebra to the right location. Anyway, the books section was trashed - there were books in the wrong spot everywhere. So what did I do. I pushed the books that I was given to their right locations. Did I fix all the other books - no. If I had started to do that, I would have never been able to finish pushing the books that I was given. I would have pushed the first book, then had to fix the books that were wrong in the 1st book's location, then had to fix the books that were wrong in the locations of the wrong books in the 1st book's location, and so on. That would have gone on for hours and hours - it would have gone on longer than my shift it was that messy.
Fixing the book section was not my job. My job was to push the books they gave me to the right locations - which I did.
Target has a team of electronics people who have the job of fixing the book section. Target has a ton of managers who have the job of making sure the book section gets fixed.
I got paid exactly the same as if I was Superman and fixed everything. The store's management gave me the same zero recognition as I would have received if I was Superman and fixed everything.
My advice is show up, do your job, and leave. What happens between when you leave and show up is none of your business. What happens outside of your section during your shift is none of your business. Do your job to the best of your ability or the best of the ability you choose to do.
