Yes ~ every single job that I've had, I have had to deal with bossy coworkers. Unfortunately, this is a reality (in the US, anyway) that we must come to terms with sooner or later.
It stinks. It's frustrating. It's stressful. It's depressing. The list goes on!
However, learning a comfortable strong way to handle yourself through these types of situations also brings a lot of personal growth and some self-confidence. I believe that many of us would come up with different words or reactions. Honestly, I am still working on finding what a comfortable reaction is for me.
Sometimes, I get snooty & tell the person to "back off!". {I don't feel comfortable with myself after this though.} Other times, I let it go. {This can feel okay for me.} Then, I've had other times in which I've tried to be as politically-correct as possible, but held my ground. {This has happened least often, but was probably the best outcome so far.} Going with the last seems like the smartest option, but it's a challenge. Emotional outbursts are a lot easier to blurt out! A double whammy comes in (for me personally) because of a brain injury & surgery, words are very difficult for me to recall. Especially when I feel emotional on the inside.
I wish you the very best at finding what works best for you.

Take care!
