HR consultancy Mercer has found that on average UK employees took 5.5 days off work last year due to sickness. This is well below the European average of 7.4 days and second lowest in Europe. The Pan-European Health and Benefits Report surveyed 800 companies across 24 European countries. Its findings put Bulgaria top of the list with a massive 22 days and Turkey bottom of the list with a healthy 4.6 days.
