Still, when I tell you about an article that I've read and recommend it to you, it would be nice if you'd acknowledge it. If I make a suggestion, even if it's not feasible, I'd like to know you read it. You don't have to even explain why you're not implementing it. A simple, "I got your note," would work for me.
I believe that much of the complaining that we CNA's do is based on the feeling that we're just the "worker bees". We're expected to do the job without any questions or input. If we do say anything, it's just buzzing in your ears, easily shut out by closing your office door.
Just a little acknowledgement would go a long way with me. I'll bet at least a few of my co-workers feel the same.
