According to a recent survey conducted by CareerBuilder.com, one in five US workers are going in to work late at least once a week, and one in ten go in late at least twice a week. The most common excuses are:

Getting caught in traffic

Problems with public transportation

Lack of sleep

Getting kids ready for school

Don't know what to wear

Pet issues

But outrageous excuses were collected as well. For instance, one person said he had to take a second shower after walking into a spider's web. Another said her husband thought it was fun to hide her car keys. And yet another said his car's left-turn signal got broken, so he made all right turns to drive to work.

The survey was taken among 3,259 hiring managers and human resource professionals, and 8,038 full-time workers from November 12 to December 1, 2008.
