We’re working it — at work.

Nearly seven in 10 online daters admit that they’ve used dating apps while at work, according to a survey of 3,000 singles on dating site Plenty of Fish. This in spite of the fact that 60% say it’s inappropriate to do this.

Sometimes they even go on actual dates while they’re on the clock. About one in four singles (22%) say they’ve gone on a first date during their lunch hour. That may be because lunch dates are attractive to potential mates — a survey by online dating site Zoosk found that messages with the word “lunch” in them got 25% more responses on average — and because they have a hard stop time in case the chemistry just isn’t there.

Sexting on the clock is common as well, with more than one in three (39% )of singles admitting to having sexted a potential mate while at work.

Many times this kind of behavior flies under the radar — but not always. About four in 10 workers say they’ve noticed one of their colleagues using a dating app at work. Furthermore, plenty of singles are keen on blabbing about their love escapades with colleagues. Indeed, more than half (55%) of singles have shared details of their love lives with a coworker, with people in their 30s being the most likely to do it (60%) have.

Career experts say this kind of TMI is generally a big no-no at work. “Talking about your love life at work can be dangerous,” says Call to Career founder Cheryl Palmer. Adds New York City-based success strategist Carlota Zimmerman: “You never know how this information might be used, or construed against you.”

Zimmerman adds that sharing the details about your love life at work may be particularly troublesome for women. “While men are [often] rewarded for their sexual prowess, women are still punished for it,” she says — and that means that even a seemingly mundane story could wind up hurting your reputation.

Palmer says that, as a general rule, “keep details to a minimum and only share what you don’t mind everyone in the office knowing” adding that if you do feel the need to share, “only share with good friends who have a track record of keeping private things private.”

This come at a time when more and more people are online dating. Fully 15% of American adults say they have used at least one online dating site and/or mobile dating app — up from 11% who reported doing that in early 2013, according to data from last year released by the Pew Research Center. These numbers are particularly high in the 18-44 age group, where more than 1 in 5 people have used these sites.
