My first job.. Are they all like this

So now that I passed my test I got my first job.

"Nurses eat their young" this is what I was told within my first 3 days of being a nurse. Had no idea what all this was about.

I have found some nurses to be rude and not welcome a new person on their unit. Not even the Unit Manager introduced herself!!!

AND the gossip! OMG! AND so many problems with CNA hiding and smoking.

Either it's like that all over or this place is just totally strange.
There are other issues I have like a total lack of professionalism on their HR side..

Tonight was my 6th night as a nurse and I was passing the meds by myself tonight. The other nights I was passing them out with the other LPN's.

So.. please let me know is this all normal. (and if it is I will be upset) or is this place just a little strange and what about me doing the med pass by myself?...
