Monday, February 7 was known as 'national sickie day' because traditionally a record number of workers stay at home on that date. Falling on the first Monday in February, it is characterised by thousands of workers calling in sick, and causing businesses to lose money. Time and motion and work experts have blamed the phenomenon on a post-Christmas malaise, the cold weather, bills to pay following a festive binge, and the fact that many weeks remain before most workers take another holiday.
