Staff absenteeism
'I'm hungover' is just one of the excuses that will be used on National Sickie Day Reuters

Employment law expert ELAS has revealed that National Sickie Day (2 February) costs the UK economy £37m in wages, lost hours and overtime.

After surveying 1,500 UK workers to find out the most popular excuses staff 'plan' to use today, the group found that the following were the 10 most common:

1. Sick or migraine (30%)

2. 'Illness' (12%)

3. Stomach bug or diarrhoea (6%)

4. Flu/cold (6%)

5. Blame relative/children (5%)

6. Food poisoning (3%)

7. Death or a funeral (2%)

ELAS added that "women's trouble", a car crash, dental emergency and "I'm hungover" have also been and will be used on National Sickie Day.

"It's understanding that this time of year can be difficult for employees as the Christmas bills roll in, people are leaving work in the dark and the next holiday feels too long away for many to look forward to," said Peter Mooney, head of consultancy at ELAS.

"Employers have become increasingly savvy to the poor excuses used by workers and it's positive to see businesses taking the steps to manage absences correctly in order to mitigate the impact it has on the success of the business.

"Having seen a 193% increase in the number of businesses we help by providing our absence assist services, we know this is an issue employees have begun to acknowledge. However, our calculations and the results of our survey still show that the cost National Sickie Day will have this year is extremely high, and there is still a lot more that can be done.

"It's important that employees know that fabricated reasons for missing work will not be tolerated. To minimise the impact false sickies have on businesses, it's important that employers take the issue seriously, recording all instances of lateness and absence, conducting back-to-work interviews and crucially, having clear policies and procedures in place which are regularly communicated to all staff."

Meanwhile, ELAS documented some of the most "far-fetched" excuses for skipping work:

• A worker called to say he couldn't come in because his girlfriend's sister was having a baby. A follow up call by the employer to verify this revealed that there was no girlfriend (and therefore no sister or baby)

• One employee claimed he only had one pair of work trousers and that they were wet because his mum had washed them, so he couldn't make it into the office

• A worker begged off work because she had been play fighting with her boyfriend and hurt her finger as a result

• A worker called to say they couldn't make it to work that day because their car exhaust had fallen off on the driveway

• A worker said they needed new tyres on their car and it would otherwise be illegal for them to drive to work

• Another claimed they couldn't afford to put petrol in their car to get to work

• One worker blamed the weather saying it was too bad to cycle to work, while another said they were too tired to cycle to work

• One employee took a leave of absence after saying his grandfather had died. The company's HR manager knew the family and bumped into the grandfather, who was very much alive and well, at the supermarket. The worker was dismissed as a result.
