Thousands of teachers have been protesting against Government plans to link salary with performance and pension changes.
Some teachers said the strike action is "a necessary evil".
@itvtynetees School closed which makes me consider issuing them a fine for my kids having to stay home in term time, good enough for them!!
On Facebook, Jane Caithness Turner says:
"I agree with them. they should voice their anger, as we all should... If we all work until 68 there will not be any jobs for youth... Teachers work harder than MPs, time for fairness."
On Facebook, Antonio Barbaro says:
"A strike is always a last resort and for a profession as dedicated as teachers to come out on strike takes a lot. Backing them 100%. Good luck to them."
Teachers from across the region set of on a march across Durham as part of a pay and working conditions strike.

Two of the country's main teaching unions will march in cities across the UK, including Durham.

It is disappointing that the NUT and NASUWT are striking over the Government's measures to allow heads to pay good teachers more.
In a recent poll, 61% of respondents supported linking teachers' pay to performance and 70% either opposed the strikes or believed that teachers should not be allowed to strike at all.
Teachers will stage two days of walkouts in October in a row over pay, pensions and workload.
Two teaching unions have announced that their members in eight areas of England will strike in October with thousands of pupils set to be affected.
Unions NUT and NASUWT said members in the East Midlands, West Midlands, Yorkshire and Humberside and the Eastern region will take part in a walkout on October 1.
Those in the North East, London, the South East and the South West will strike on October 17.
A national strike is likely to follow and take place before Christmas.
The two largest teachers' unions, who have announced they will go on strike before Christmas, have criticised Education Secretary Michael Gove for his "relentless attack" on the profession.
The Secretary of State needs to take seriously the very deep concerns and anger of teachers and school leaders.The relentless attack on the teaching profession is damaging the morale of teachers and undermining the education of pupils.
The Secretary of State has the opportunity to avoid further national strike action by demonstrating that he is willing to engage seriously on the issues that we have put to him.
Michael Gove is well aware that under his time as Education Secretary, teacher morale has plummeted. Teachers are angry at the Government’s continual undermining of their pay, pensions and working conditions.
Strike action is always a last resort for teachers and they are very well aware of the difficulties that this causes for parents and pupils. Teachers, however, have been left with no option. If we do not take a stand now to defend the profession, then the consequences for teacher recruitment and education will be disastrous for all.
The two largest teachers' unions have announced a national strike in England before Christmas over working conditions.
The NUT and NASUWT represent nine out of 10 teachers in the country.
