The silly season is upon us—the holiday rush, the shopping hangover, the December calendar crowded with obligatory holiday parties overloaded with crudités, shrimp cocktail and bad wine.

And so what once might have been viewed as a foreboding sign of corporate distress could sound pretty good this time of year: More companies are saying they just don't do holiday parties anymore.

On Monday, the Society for Human Resource Management released its annual survey about end-of-the-year office fêtes. In it, 30 percent of the H.R. professionals who responded said their companies do not usually have year-end parties for all employees. That's the largest percentage recorded since the organization started doing the survey in 2009.

More are saying a December sans le soiree is now just business as usual, rather than a blip for the current year due to budget constraints. This year, only 6 percent of the managers surveyed said their company had cut back on the office party due to financial challenges, compared with 9 percent in 2013 and 20 percent in 2010 and 2009 amid the recession (there was no survey in 2014).

"That stood out to me," said Evren Esen, director of survey programs for SHRM, in an interview with The Washington Post. "It may be that they’re not directly relating it to financial challenges, but they did cut it out before and may have felt employees don’t really seem to be missing it."

Esen said it'll be interesting to see if the trend continues. "Maybe it's one of those things that's not as appealing to employees anymore," she said. "Millennial employees may also have different expectations of the workplace and how they want to spend their time at work."

She noted there could also be concerns about the risks of employees who overindulge in all those passed glasses of cheap chardonnay. While roughly similar numbers of H.R. managers said they would serve alcohol this year—59 percent, down from 61 percent in 2012, the last time the question was asked—many more said they planned to offer drink tickets to regulate employees' consumption. Seventy-one percent said they were going to take that strategy this year, compared to 57 percent in 2012.

The survey also found that more H.R. managers plan to close early on the day of their holiday party (22 percent, up from 12 percent in 2012). And while it's not surprising that few companies are giving out nonperformance-based holiday bonuses anymore—most companies have moved to merit-based awards—the drop in H.R. professionals saying they're giving out Christmas gifts is notable (23 percent, compared with 32 percent in 2013).

But whether or not companies have realized employees might savor one less holiday party obligation, they don't seem to be loosening the reins on holiday shopping at work. For the first time, the survey asked about what limits companies place on letting their employees hunt down the latest Star Wars gadget or Girl Scout Cookie oven while on their computers at work. Fully 32 percent said it wasn't okay for their workers to do so, even during lunch or breaks, and only 13 percent said it was acceptable at other times during the workday if an employee's work was on schedule.
