We have discussed about noise in working environment where we are a law firm which requires lawyers and staff act professionally. At the management level, we have expressly informed many times our concern regarding the noise, but some of you still keep doing. You should concentrate more on work rather than making noise to disturb others. If you have nothing to do, I highly recommend that you should ask for more work from your supervisor instead of disturbing the others. Please be aware that shouting is unacceptable in all working places, unless your occupation is singer.
