(Full disclosure – I’m a teacher).
Home/school contracts are a good idea on the surface (we have one), but actually have very little substance. Much better to actually try and build a positive relationship between school and parents by other means (community projects, good quality communications, getting parents involved in school in practical ways, etc.).
Of course, there is no ‘right to strike’ in UK law (although IIRC EU legislation and High Court rulings earlier this year run strongly contrary to that), so you could always try a legal challenge against your children’s teachers.
My own union has not yet made a decision on strike action. If I’m honest I would be torn – I understand the union/profession’s stance, but striking as a teacher doesn’t personally feel right to me.
