The one problem I can see with you being perceived as bossy is the RN/CNA Dynamic. Just delegate in a respectful manner. I've found I like to say things like "Can you please do such and such and I can get caught up on my charting?" Always say please, and if you can see your busy say something like "I know you're busy and you don't have to do this right now, but can you....." Ask, don't order.
In nursing it is okay to be fast and task oriented but you really have to be flexible because it's only frustrating because things change quickly....an admission is never convenient, a patient IV infiltrates and will throw your whole schedule off.
I'm more of a get organized as possible, but go with the flow..sometimes fly by the seat of my pants kind of worker. I work med surg.
Just yesterday, I had to endure a doctor upset with me calling him at 7:30pm with something he didn't deem important and had him lecture me. I'm nearly 60 years old with 27 years experience and a college degree. I could have explain why I felt it necessary but I merely said "just wanted to make you aware to cover myself, thanks." and let it go. I've been to too many case reviews and depositions where it wasn't documented that the doc was made aware of a certain situation prior to things going sour and I cover my butt I don't care what the doc thinks. Choose your battles.
You never know what another person is going through and I might have just pushed the wrong button at the wrong time.
Also, I know when to speak up when behavior is unacceptable, but I've also let go of a lot of expectations of others. Just because I'm a certain way, another person doesn't have to bend to my will and work as I do. I do get frustrated with some people's lack of work ethic, but they usually don't last long.
Finally, the refrigerator is not my responsibility. My lunch is packed and sealed and sanitary. Other people can leave their food in there a year and it wouldn't bother me.
