Boris Johnson is opposed to the scale of working from home seen during the pandemic becoming permanent, according to government sources.
The Prime Minister is said to be supportive of encouraging people to return to offices once it is safe to do so, having hoped to ease working from home guidance this month.
The Government is in favour of proposals to boost flexible working, including the right of employees to request changes about where they work at the start of their jobs.
But Downing Street argues that backing the change is different from wanting to see millions of people who were in offices before the pandemic continuing to work full weeks from home.
The Prime Minister’s official spokesman said: "It’s important to stress that there are no plans to make working from home the default or introduce a legal right to work from home."
A senior government source told The Telegraph: "The changes are very much about making flexible working easier for people so that it is possible for working parents to pick up their kids, making life easier for carers, etc.
"What we’re not looking to do is make working from home, as people have done from Covid, a permanent thing. I don’t see us ending up there in any way."
Current Government guidance urges people to work from home if they can in an attempt to limit the spread of Covid, and the lockdowns have triggered debate about whether such work practices will become a longer-term feature of life.
Supporters of more flexible working argue that it helps work-family balance, for example by making it easier for parents to share child-raising responsibilities. Opinion polls suggest those who have been working from home during the pandemic favour continuing in some hybrid work arrangement after lockdown.
But critics question whether it has negative impacts on productivity and workplace cohesion or lead to social isolation with less in-person interaction with colleagues.
Jacob Rees-Mogg, the Commons Leader and a member of the Cabinet, argued in Parliament on Thursday that employees should be able to go into the office if desired.
He said: "The guidance is clear that if people need to go into work they are allowed to go into work. If employers think that they need their employees to come into work, they are entitled to ask them to come into work.
"Even within the civil service, managers are advised to accommodate requests to work in the office when home working is not suitable for well-being reasons.
"It is really important that we get back to normal. We want to have vibrant towns and cities, we want people coming back into work, and we want commuting systems – trains, buses and so on – that are financially viable, and that means people coming back to work."
Mr Johnson told The Telegraph last month he had hoped workers would have been able to get back to the office if required from June 21. "If their work requires them to go back to the office then they should go back to the office. But we’re not at that stage yet," he said early last month.
The plans were pushed back when the final step of lockdown in England was delayed to July 19.
