Figures released by the government agency on Tuesday show that unemployment continues to rise as a result of the economic downturn caused by coronavirus, with redundancies reaching their highest level since May to July 2009.
Unions warned the UK was on the precipice of an unemployment crisis and urged the chancellor to reform his job subsidy schemes.
From June to August this year, the number of unemployed people in the UK jumped by 138,000, increasing UK unemployment to 1.52 million.
As a result, the rate of unemployment now stands at 4.5 per cent, up from 4.1 per cent in the previous quarter.
Young people have been hit hardest with employment among those aged 16 to 24 dropping to a record low of 3.54 million.
In total, 673,000 jobs were lost between March and September.
However, the true unemployment picture is likely to be significantly worse than the headline figures suggest because furloughed workers are classified as employed.
Some 4.8 million people were on the Job Retention Scheme in September. It comes to an end in little over two weeks, to be replaced by the less generous Job Support Scheme which incentivises employers to make staff redundant rather than keeping them on but reducing their hours.
The official data show that weekly hours worked, which some economists believe give a more accurate picture of the jobs market, are well down on pre-pandemic levels.
Jonathan Athow, deputy national statistician at the ONS, said: “The latest monthly tax numbers show that the number of employees on the payroll was little changed in September.
“However, in total there were still nearly 700,000 fewer than in March, before the lockdown.
“Our newly adjusted survey figures show that in the latest period almost half a million fewer people were in work than just before the pandemic, while almost 200,000 others said they were employed but were currently not working nor earning any money.”
The ONS data comes the day after some business leaders expressed their disappointment at Boris Johnson’s new three-tier Covid-19 alert level, which they fear will lead to more closures and job losses unless further government support is forthcoming.
Responding to the latest figures, Rishi Sunak, the chancellor, said: “I’ve been honest with people from the start that we would unfortunately not be able to save every job.
“But these aren’t just statistics, they are people’s lives. That’s why trying to protect as many jobs as possible and to helping those who lose their job back into employment, is my absolute priority.”
TUC general secretary Frances O’Grady, said: “We are on the precipice of an unemployment crisis. Ministers must act now to protect and create jobs. The expansion of the job support scheme is a step in the right direction, but it still falls short.
“Wage replacement should be 80 per cent for businesses who have to shut. We need a more generous short-time working scheme for firms which aren’t required to close but will be hit by stricter local restrictions. And self-employed people in local lockdown areas need help too.”
