Some 27 teachers in the NUT union at South Chadderton School in Oldham went on strike last Thursday over changes to pay and the suspension of their union rep.
The school's management have reneged on a deal reached earlier in the year after the school saw strike action to prevent pay cuts.
Over 20 picketed the school as strikers were joined by their supporters.
Banners from nearby Wigan and Bolton NUT branches, solidarity from suspended Unison steward Karen Reissmann and the many messages of support read out from local schools, boosted the strikers' confidence.
