Some part-timers fell lucky because the strike day was on a day when they don't work. You were unlucky with it falling on a work day. You may not have lost a day's pay but you're worse off than a 0.6 teacher who supported the strike but didn't lose any pay. You're lucky that they use the 1/365 calculation. I believe some LA /schools use the 1/195 calculation meaning that the day's pay + the pro-rata holiday pay is forfeit.
