Scotland’s largest teachers’ union, the EIS, has rejected a 9% wage increase. The union intends to start a strike ballot, and then engage in a walkout if management does not offer a more favorable wage increase. This pay dispute has been ongoing, with management only having a fortnight to offer a better wage plan before the strike ballot will occur. In order for the teachers to strike, 50% of the members in the bargaining unit need to be present for the vote and at least 40% of the members of the unit must be in support of the strike.
