As Dr Matthew Cole, assistant professor of technology, work and employment at the University of Sussex, said Frindall is among a new generation who are turning to side hustles due to the cost of living crisis.
“If people earned higher wages and things cost less, they wouldn’t be working as much”, he told the BBC.
According to him, this was partly because real wages had not recovered since the 2008 global financial crisis.
But he added there also are not as “many decent jobs” with stable contracts and career paths as in the past.
“Side hustles are a coping mechanism,” said Cole, adding that many people were not working extra “out of passion”.
