Unions in the UK have warned that schools should not be able to reopen unless key measures are set in place.
The TUC (Trades Union Congress) is urging government ministers to work closely with unions to agree a way forward.
There had been speculations that schools may return in England from June 1, but it was ruled out in Scotland and Wales.
The Department for Education in England said that it would follow the scientific advice about the right time to reopen schools.
In the wider aspect of the coronavirus lockdown, the Welsh First Minister, Mark Drayford, has acknowledged that extending the lockdown could damage people’s sense of mental well-being.
He said: “We should all be anxious about how long it can be sustained.
“I hope, though, that changes to the regulations will help people to do the biggest thing that we are asking of them”.
People in Wales are set to be allowed to go out and excesrsise locally more than one time a day and garden centres can reopen.
