In a new survey by CareerBuilder, cat hiccups, a disgruntled roommate, and a governor's phone call are among this year's most unusual excuses employees gave for being tardy. Sixteen percent of workers reported they arrive late at work once a week or more, up from 15% last year. Twenty-seven percent of workers arrive late to work at least once a month, up from 26% last year.

While employers are more flexible about work schedules and start times today, excessive tardiness can have serious consequences. Over one-third (34%) of employers said they have terminated employees across industries for being late.

Traffic, sleep schedules, and weather conditions are the top three causes for late arrivals to the office, according to workers:

  • Traffic31%
  • Lack of sleep18%
  • Bad weather11%
  • Getting kids to school or daycare8%

Other common reasons for tardiness included public transportation delays, pets, spouses, watching TV, and Internet usage.
