Essex County Council has apologised for a payroll error which could mean as many as 20,000 teachers and school staff won't be paid on time this month.
Staff would normally expect to get their salaries today, but they will now have to wait until Tuesday 29 August due to the problem which is being blamed on an 'internal process failure'.
The Council have written an apology to everyone affected and have also launched an investigation.
“We are extremely sorry that this error happened and we have launched a full investigation to understand why it occurred and ensure it does not happen again," Councillor Louise McKinlay said.
“We will offer all the help, support and advice we are able to provide to affected schools employees tomorrow and will have a team standing by to deal with calls.
“Because the actual pay date for affected employees is Saturday 26 August, standing orders and direct debits due then should be processed on Tuesday after the bank holiday, but we will be able to advise schools employees with any concerns they may have.”
The council's payroll team will be available to offer information and advice from 8.30am to 4.30pm today, while concerned school employees can also call 03330 135859.
