ESSEX County Council has warned up to 20,000 staff in the county's schools they may not get paid as expected today, Friday.

The county council, which oversees the payroll in many schools, says an internal systems error means salary payments may be delayed until Tuesday.

This means they won't be paid in time for the Bank Holiday weekend.

The county council has apologised to staff affected and issued an apology.

The council's payroll team is on hand today (Friday) from 8.30am to 4.30pm to issue advice to those affected.

The number to call is 03330 135859.
