Recruitment experts have also said more of us will need to retrain as the world of work changes rapidly during these uncertain times.

Chris Kruger is a chef, but now he is training to become a gas engineer.
He described the lack of work and job uncertainty as "very stressful and very worrying".
Mr Kruger said: "Not knowing whether things were going to go back to normal, whether I would still have a job, and the situation at home expecting a baby and so forth, and my partner also being in the hospitality industry.

He added: "I just said, no, I need to utilise this time to study."
