SCHOOLS are expected to bear the brunt of strike action on the Island called for July 10.
More than 1,300 letters went to IW UNISON members this week calling on them to take part in a national pay strike.
UNISON wants an improvement in a one per cent pay offer and for a focus on the wages of lower-paid members, many of whom receive little more than the minimum wage.
The National Union of Teachers (NUT), the GMB and Unite plan to strike on the same day, promising much greater disruption than the NUT strike in March, which closed two schools and disrupted others.
This time a broad range of IW Council services will be hit as well as schools.
"Our feeling is the national ballot result of 60 per cent in favour of a strike was reflected on the Island," said UNISON branch secretary Mark Chiverton.
"UNISON members feel the one per cent pay offer is entirely inadequate and they will slip even further behind than they have in recent years."
The IW Council said it was putting in place contingency measures in discussion with unions.
