The government should help by reallocating some workers in sectors that have temporarily shut down to parts of the economy facing labour shortages, reckons think tank the Institute for Fiscal Studies.
It pointed out the coronavirus pandemic has led to sharp falls in labour demand in many corners of the economy, while there are acute labour shortages in other sectors.
To help, the government should remove barriers to taking up temporary jobs, facilitate worker loans between firms and sectors, and subsidise retraining where appropriate, it said.
"There is an urgent need to reallocate some workers," said Xiaowei Xu, a senior research economist at IFS.
"At a minimum, the government should remove barriers to fill much-needed roles."
