The fuel crisis could see schools return to online learning as teachers struggle to get to class, it's warned.
With drivers still facing long queues at the pumps and stations closing because they've run dry, it's left many workers unable to get to their jobs.
With teachers and education staff among them, some schools have already warned they may have to resort to remote learning again if the situation isn't resolved.
SurreyLive reported how a top independent school is considering a temporary move to online learning due to fuel shortages.
In an email sent to parents, Lingfield College headmaster Richard Bool said the current 'petrol crisis' could potentially disrupt the school.

"We sincerely hope that it won't be the case, but if it becomes necessary to temporarily move to online learning, we will consider this as an option," he said.
"Clearly, we have no desire to go back online so soon after the challenges of the last couple of years, but we cannot exclude the possibility that it may be necessary."
Unions are now calling for teachers and school staff to be prioritised to prevent such disruption.
Dr Patrick Roach, general secretary of the NASUWT teachers’ union, said the shortages are expected to cause 'serious difficulties' for education provision.
He said: “Following many months of disruption, it is now of the utmost priority that the government takes steps to ensure that schools and colleges remain open and that teachers and education support staff are able to get to work.
“For many teachers, the use of public transport is simply not an option, with many schools in areas that are not easily accessible other than by using private vehicles.
“The government must urgently consider making teachers a priority group for access to locally available petrol and diesel fuel supplies.

“Without such intervention, many teachers will struggle to get to their places of work on time, adding to the daily uncertainty and disruption faced by children and young people.”
The warnings come as Army tanker drivers have been put on standby to help combat the crisis.
Military drivers will get specialised training in preparation for their deployment as panic-buying continues across the country for a fifth day.
Certain HGV licences will also be extended to help tackle the issue, ministers announced on Monday.
