I don't get it. I don't get how your colleagues who ate lunch with you everyday and when something crops up they wouldn't hesitate to throw you under the bus.

I work in a really small company so daily we have to clear the dustbin near our desks.

Yesterday after I emptied my rubbish into the plastic bag, my colleague was the one who took it and I went to take out the rubbish on my table.

Today, when I came into office, she loudly said " Jaemin! You forgot to take out the trash yesterday!!!" 

Right in front of the boss and everyone.

If I argued with her on the spot, she would insist that I was the one who forgot to take out the trash and it would end up with both of us on the bad side of the boss.

So what do people do in that situation? Keep quiet and get blamed for it, I guess.

It's not the first time this happened and I just keep letting it slide. No wonder my bosses think I'm unreliable.

What else can I do?
