National Education Union members at seven Island secondary schools will walk out on Tuesday 19 March for the whole day.
Grainville, Haute Vallée, Hautlieu, Jersey College for Girls, Le Rocquier, Les Quennevais and Victoria College are facing the threat of closure as teachers prepare to strike.
It is the latest development in a long-running dispute between public sector staff and the States Employment Board.
NEU Regional Secretary Andy Woolley said: ‘We have informed the States last weekend that there was an overwhelming rejection of their offer of just the retail price index rise plus 1.3% for 2020 with no change to 2018 and 2019 when the imposed awards were well below inflation. Members have contacted us to confirm that they feel it is unacceptable to still have a fall in their standard of living over the three years.
‘We have had no further contact about re-opening negotiations so we have no alternative but to re-instate our strike action for this date. The ballot we conducted also allows us to call out primary schools in future and to repeat the action if necessary but we hope that the States Employment Board will now realise the strength of feeling amongst its teacher employees about continual falls in their standard of living and demonstrate in real terms of a fair pay rise that they really mean it when they say they value what our members do for the young people of Jersey.’
