Bosses don't work together well sometimes...

I have found out that I don't think bosses work together that well sometimes. For instance, at my job Boss A. tells me how to do something. The next day Boss B. is on duty and tells me how to do the exact same thing. Then the third day, Boss C. tells me the same thing....Again. At this point Boss A. has forgotten that they told me how to do that one thing, so they remind me again. And then the same thing happens with bosses B and C. Eventually after bosses A. B. C. tell me how to do that one thing around 5 times, they get it in their heads that they have told me.

This is happening a lot...

And it's quite annoying
