I have had similar issues and am wondering how my colleagues will address them:
There are two (particularly one) employee who constantly talk. They leaves their work areas to discuss simple things that turn into a social talk, giggling and laughing goes on for several minutes. They keep forgetting to schedule follow ups at check out, there are duplicate appointments every week, do not address DNKAs, forget to give vaccine information sheets, .... and it is not funny any more. Any suggestions to improve my office system to minimize these issues?
