Shadow chancellor Anneliese Dodds is to accuse the government of mismanaging billions of pounds spent in response to the Covid-19 pandemic.
In a speech to party members on Monday, she will accuse ministers of a “cavalier” approach to public spending during the crisis.
But she will call for firms in struggling sectors to get extra support to retain workers, or provide training.
The government accused Labour of offering “recycled” economic plans.
Ms Dodds will call for a change in approach to managing the economic downturn during a speech to Labour’s online conference, which will end on Tuesday.
She will unveil proposals for a jobs recovery scheme targeted at sectors that have been closed or on reduced capacity because of social distancing rules.
In a bid to stem job losses, she will also call for £3bn in funding to be brought forward to retrain the unemployed or those at risk of losing their jobs.
She will urge ministers to provide additional support to viable but indebted firms due to start repaying government loans from next spring.
