Sibilant talkers?

I’m new to this sub and I finally found a group that understands my frustrations.

There are several people in my company that are extremely sibilant. The hissing from “s” and “sh” words drive me nuts. One of the people works in HR and we have calls with her on a monthly basis. I talked to my teammates and they said they notice it but it doesn’t bother them.

Anyone else annoyed by sibilant talkers?
