How should I handle?

Forgive me if I am posting this in the wrong place. It has been a while since I have visited the site.

I am a CNA in Colorado. I recently started a new job at a rehabilitation facility, so far I love it. I've done nursing homes in the past and felt more of a hospice nurse which I am not suited for.

My point: I am not a brand new CNA, but I'm feeling as though one CNA in particular sees me this way. Her attitude is just mean and unprofessional. For example, I worked Sunday with her. As soon as I got on the floor, she handed me the patient list and therapy schedules for a particular hallway, then switched me to a different hall saying well this hallway is easier and I'm making your life easier. I was on the previous hall the day before and knew the patients, it was not that difficult. I just put my head down and get to work. The hallway that I ended up working was very difficult. Multiple call lights going off at the same time, especially during trying to serve breakfast and lunch. I always answer my call lights before anything. There have been some hiccups with dietary; serving has been slow, running out of silverware among things. After answering several call lights, I came back to the dining room to get my room trays and serve..She had already set my trays up and said I've caught you up in a snarky tone, I just smiled and said thank you. She is not dietary; she is a CNA, not a manager of any kind.

I have been on this job a few weeks now..I certainly don't want the reputation as a tattle-tell, but her attitude affects not just myself but other workers and then trickles down to our patients.

She pulls rank because she has been with this company for 6 years I think..but still a CNA..

How do I handle this? I feel bullied.
