I'm afraid the information in there is completely wrong Galena
Here's the guidance from my union who are not striking
Reporting for work
Firstly, and most importantly, you must make yourself available for work as usual. If the head/principal decides to close the school/college, you should ask what s/he wants you to do e.g. work from home or from an alternative venue. Alternatively, if your school/college remains open you must inform the head/principal that you are available for work and ask what s/he wants you to do e.g. come into your usual workplace, work from a different location or work from home.
Covering for striking colleagues
When colleagues are taking industrial action but ATL has not balloted, you should work as normally as circumstances permit but you should not undermine your colleagues' action. This advice also applies to supply teachers. Members who are under pressure to cover for striking colleagues should contact their ATL rep or branch secretary for further advice and support.
In the case of maintained schools, you should be aware of the provision in the School Teachers' Pay and Conditions Document that all directions of heads are subject to the requirement of reasonableness: if an instruction is clearly unreasonable, it can legitimately be refused.
ATL would normally consider it unreasonable for you to be asked to:
<strong>take over the work of colleagues engaged in industrial action,</strong> other than in exceptional circumstances such as genuine emergency
<strong>undertake a teaching load greater than usual or to accept additional responsibilities or duties as a result of colleagues taking industrial action</strong>
<strong>agree to the amalgamation of groups of pupils or students or to the division of one group between others as a result of colleagues taking industrial action.</strong>
The rarely cover contractual provision should not apply in relation to strike action. *Teachers should not be required to cover for absences which are know or which can be foreseen, and in the case of strike action the NUT will have written to tell schools the date of action and that they are asking their members to take action in line with statutory requirements.
NASUWT guidance
Where members of another TUC-affiliated trade union are involved in industrial action, NASUWT members should:
make clear to the headteacher/principal that they will be reporting for work as normal;
make clear that they will not accept any variation to their contracted duties and/or undertake the timetabled or other responsibilities of those engaged in action, including taking into their timetabled lessons pupils from classes of teachers who are involved in strike.
Where a school/college remains partially open and certain classes/year groups are sent home, NASUWT members should not agree to timetable variations to accommodate classes or pupils who would normally have been taken by those taking action. The NASUWT would need to establish with the headteacher/principal that members who are working with their normal classes will be able to access all of the necessary services to ensure the health, safety and welfare of themselves and the pupils.
