Staffing concerns - short vent

I don't know what eveyone else's working conditions are...just my latest experience. It seems lately, that the CNA's are not calling in when going to be late, ill, ill child, etc. They just don't show up or call!!! I do know that management treats the CNA's horribly and it just burns me up. The nurses have met as a group effort to talk with management regarding our concerns, but, as usual, get the regular reply, "They just don't want to work". These CNA's work their rears off and with no overtime allowed. I am so thankful that the CNA's who do come to work really put their hearts into their work. Please know that you are sooooo appreciated and I tell you that every day that we work together..

But, it is getting to the point where we are having to work so short each shift, that my med pass, treatments, orders and other paperwork, get way behind. I end up with overtime and then I am chewed out. I'm so ready to write my letter of resignation, as I feel my license is on the line, everytime I clock in. It's getting to the point where I check before clocking in, to see if I am going to have staff for my shift.

If I decide to look for another job and resign from this position, is there a tactful way, to let management know that I am leaving, due to the CNA shortage and treatment? I know what I would really like to say...LOL!!!
