The labor market is “worse than the 1970s,” with gigantic rail strikes in the U.K. suggesting things are coming, according to Nobel Prize-winning economist Christopher Pissarides.

Britain’s RMT Union confirmed Monday that planned railway strikes will commence this week after talks with train companies couldn’t reach an agreement over jobs, pay and conditions. Around 80% of trains are cancelled, with further strikes planned later this month and in July.

Pissarides, Regius professor of economics at the London School of Economics, told CNBC on Tuesday that labor markets are going through “some of the most difficult periods” he has seen.

“It’s even worse than the 1970s, in the sense that we need to make bigger adjustments in labor markets. We have new technologies bringing on automation and, in fact, the trade union leaders are complaining about job losses, about ticket offices – that’s due to the new technologies,” he said.

Furthemore, global eonomies are struggling with soaring inflation, particularly in food and energy, in large part because of the Russian invasion of Ukraine.

Pissarides, who won the Nobel Prize for economics for his work analyzing job markets, said there is “no way we can avoid the pain from that,” but that it needs to be distributed throughout the economy.

“There aren’t many sectors of the economy which have strong unions. We don’t have big nationalized industries like we had in the ’70s when the whole of manufacturing was going on strike, and therefore that makes it very difficult to say: ‘Those of you who have strong unions, we’re going to give you full compensation for these external shocks, and let the others bear all the burden’,” Pissarides explained.

“The spiral is not quite there yet, but giving pay rises that match or are close to matching the inflation that the Bank of England is forecasting will get us very close to a spiral, and we might see it, and if that happens, it’s going to take much longer to get rid of inflation,” he said. 

“Remember in the ’70s it took at least 10 years to get inflation and it was very tough in the end, it was the Thatcher policy that caused so much unemployment just fighting inflation. That’s certainly not something that we want to see this time because we’ve learnt our lesson hopefully.”
