Boss changed the rules last minute then yelled at me, what do I do?

So I wanna ask you guys how I should handle this. I’m 36, work as a shop staff in Udon Thani. About ten people at the shop, and the boss is from the same area and runs everything by themself.

Two weeks ago the boss told us to do a new kind of stock arrangement — separate stuff according to the list they gave and send a weekly report. I followed everything. Adjusted the schedule, rearranged the shelves, changed the labels, spent about two hours a day on it on average. Took some getting used to and it was a bit tiring but I managed.

Then the other day around 10:30am some head office staff came to inspect. The boss quietly changed the way of storing things again without telling the team. When the head office people looked, the stuff I’d arranged the previous way got ripped apart in the meeting for being messy, not organized, wrong procedure — even though I’d been doing exactly what the boss told us to do. I got called in and scolded alone, with that disappointed tone and look, like super harsh. I’m confused and it hurt.

I was singled out and scolded, even though this should’ve been communicated within the team first. It’s not fair to send someone out front and then let them take the blame because the boss changed the policy without telling anyone. I don’t want to disobey orders, but it’s unfair. They didn’t ask or prepare the team at all, just grabbed a little red pen I had and started circling and pointing that it was wrong. It stung.

I feel really uncomfortable, like I’m the only one being blamed. I don’t want the shop atmosphere to be tense, but I’m scared if I speak up directly I’ll be seen as disloyal. Should I keep it to myself or clear it up straight away? Wait for things to calm down or talk now so this doesn’t keep happening? lol

Typing on my phone, planning to talk after work for like half an hour or call around 8pm, but I’m worried talking will just make things worse. Feeling awkward. Has anyone been through this? Please give advice, what should I do? T_T
