One idea for a speech at a holiday party is to thank everyone at the party as well as a supportive partner during the speech, according to Ragan.com. Another tip for holiday speeches is bringing up personal and professional milestones and accomplishments that occurred during the previous year.
If you're giving the speech to a small group of workers, specifically mentioning and praising each individual is another possibility. A holiday party speech is not the appropriate place to criticize, so only highlight accomplishments during the speech. Ragan.com also recommends that the speaker keep the speech brief, to keep the focus of the night on the party.
