Thirty-six percent of workers say they discuss politics at work, and 43 percent plan to address this year's presidential election with co-workers, according to a national CareerBuilder survey conducted by Harris Interactive.

Although most conversations about politics are good-natured or even-tempered, 23 percent of respondents who have discussed politics at work say they have participated in heated discussions or fights with a co-worker, boss or someone else higher up in the organization. One in 10 respondents say their opinions about co-workers have changed after they discovered their political affiliations, and most say it negatively changed.

The survey reveals that men are more likely to share political opinions or commentary at the office as 44 percent of male respondents discuss politics at work compared to 28 percent of female respondents. Men are also more likely to report an altercation with a co-worker over opposing political views at 25 percent compared to 19 percent of women.
