This week's rail strikes "will cause misery for millions", a government minister has said, but insisted public sector workers need to be "realistic" about pay rises.
Speaking to the BBC, Chief Secretary to the Treasury Simon Clarke said the government has to manage expectations on pay, saying double-digit wage hikes aren't affordable.
Clarke said he didn't want to see "inflation-busting" pay rises for public-sector workers because that would risk "baking in" higher prices through what's called a "wage price spiral".
Asked whether the government is happy to see the strikes take place for political reasons, Clarke said they "absolutely don't want them to go ahead" because they will "cause misery for millions of people".
"It is in everyone's interest, passengers and tax-payers alike, that we find a way forward," Clarke added.

"There is no suggestion of a pay freeze, but we do need reforms - the rail industry is currently unsustainable and not fit for the 2020s.
"We are asking for the rail industry to reform itself sensibly. We need this to be resolved," Clarke says.
The government has faced criticism for not stepping into talks between the rail employers and the RMT, but Clarke says he doesn't think the union will negotiate in good faith.
He says it's been reported that RMT general secretary Mick Lynch will "not negotiate with a Tory government" so that limits the chances of a "sensible" negotiation.
"We don't sit around the table with the trade unions - we're not the employer," Clarke says.
