I'm a receptionist on the front desk/main reception in a fairly large building. It has a small foyer area and doors leading off to different parts of the building where others work. It is NOT a waiting area and has no seating.
I take all of the calls coming into the building, which can be very frequent, and deal with issues or I direct calls to other parts of the building.
My colleagues who work throughout the building, of which there are many, will often pass through reception having very loud conversations, or will use the foyer area to stand and have very loud conversations, as it often tends to be an area where they pass through and bump into each other.
One guy will come out of his office and use the foyer area to pace up and down and have very loud conversations on his mobile, often work related, sometimes not, presumably so he doesn't disturb the people he works with in his office.
The other day (this occurrence is an example of the sort of thing that happens regularly) two of the managers came bursting through one of the doors right by my desk, one of them mid-peal of loud high pitched laughter, and continued having their very loud and enthusiastic conversation standing at and leaning on my desk, a foot away from where I was having quite a sensitive conversation on the phone with someone.
Due to the nature of the work, some of the calls do need handling quite delicately and sensitively. I had to ask them to repeat themselves with a finger in one ear.
But it's like my colleagues barely notice I'm there and often in the middle of a conversation on the phone. This might be the first contact this person makes and they hear all that racket in the background.
The other day there were two loud conversations with two separate groups of people going on in the foyer and the phone rang and not one person thought to lower their voice.
I am worried about speaking up because it's often the big managers who are high above me that are doing it, and because I have been there less than a year, the other receptionist has been there years, and I think it's obvious it will have come from me.
YABU - it's part and parcel of working on a front desk and in main entrance area, it's your job to deal with it and it's not a big deal.
YANBU - You should speak up, it's making it difficult to do your job, and they are being inconsiderate.
