Med errors

So I’m the house manager ( basically just in title, I work a regular DSP shift, I just make the schedule lol) I worked 6 days this week all the meds were fine. Everything accounted for even the boost was fine. I came back on Monday to pass the am meds, and literally all gone to shit, missing pills, missing boost. Like ugh I left the house Saturday night and everything was fine. I tell them to double count, take your time. And I don’t have any authority to write people up, it’s just very annoying. I don’t know any other way of telling them they need yo stop with the med and documentation errors, they won’t listen…
