How can the Deaf or Hard-of-hearing employee communicate with their colleagues?

writing on paper

by emails for greater clarity on work instructions

By sign language.  We know of hearing colleagues who take up sign language classes to better communicate with their deaf or hard-of-hearing colleagues

In meetings, the deaf can have a close buddy at work to assist in taking/typing notes so that Deaf is kept aware of the discussions. The Deaf can then “voice out” their professional opinions and thus be able to contribute their work ideas in the meetings.
