Julian Acquari, MD of Monster UK & Ireland, said: "Despite the slowdown in the UK's economy and the problems in the Eurozone, it is encouraging to see an increase in online job opportunities since this time last year. This aligns with recent ONS unemployment figures, which show a reduction in joblessness.
"The increase in online recruitment is led by the engineering sector, which has seen a 20% rise over the last year, as well as significant growth in a range of occupations including HR, hospitality and tourism and construction. When we see opportunities spread across a range of industries in this way it's one sign of stability."
