I work at a bank in the United States. Every month we have a two hour department meeting and the head of Loan Operations talks first and gives a run down of the past few weeks activities. What bothers me the most about these meetings is that it is hard to follow what she is saying because she says "you know" so often. It's distracting and it is like someone scratching fingernails on a chalkboard.
I am thinking of providing constructive criticism by either telling my supervisor about this or telling her directly that her use of "you know" so often makes what she is saying hard to follow. But would I be out of place for giving criticism to my boss' boss? Can I suggest she work on cutting down or eliminating the phrase "you know" by practicing or taking a class? Or would this be insulting? I would like to point out a way to improve from one professional to another, but I don't want to come across as offensive.
Update -- Thanks guys for all the feedback. The consensus is not to let her know her "you knows" are hard to hear. I get it. Thanks.
