The National Education Union will hold a ballot to consider industrial action after rejecting a 7.9% inflationary pay offer from the States.
The States Employment Board says it's disappointed and that threats of strike action by the unions is 'unhelpful'.
Vice Chair of the Board, Constable Andy Jehan says they recognise the vital role teachers play in the success of the island.
"We have made a fair pay offer of 7.9% to all pay groups and this has been accepted by the majority of employees.
The requested pay rise by the NEU is out of step with other pay negotiations, as we continue to face high levels of economic uncertainty which creates pressure on public finances.
We will continue to meet with unions and engage positively with them in order to reach a successful resolution."
