Seven teachers in the NUT union took part in a solid three-day strike at Joseph Locke primary school in Barnsley last week.
The dispute is in defence of one teacher who faces a pay cut of £4,000 a year.
The teachers have now struck for ten days since the beginning of December and have taken more action than any other strike in Barnsley NUT history.
The strikers are getting support from other unions – three of them addressed a UCU lecturers’ union meeting at Barnsley college last week, and PCS civil service union members have visited their picket line.
UCU and PCS members are planning to build a solidarity picket with the teachers for Wednesday of this week – the next planned strike date.
The strike campaign forced the headteacher to agree to talks – which took place on Friday of last week but they failed to settle the dispute.
Management offered to go to binding arbitration and members were discussing their response as Socialist Worker went to press.
If the dispute is not resolved the teachers will strike again on Wednesday and Thursday of this week.
