TEACHERS could strike again in the new year over changes to term times.
Nottingham City Council has decided to press ahead with plans to alter holiday dates in its schools.
Teacher strikes earlier this year led to school closures.
The National Union of Teachers' is considering whether to ballot members on strike action.
Ian Stevenson, regional secretary, said if action is taken, it is likely to happen in the new year.
He said: "It's with our action committee right now. There's no rush from our point of view. We are in a position where we can take our time to look at this and decide how and when to take action.
"We are campaigning against this and will be considering various strategies for how we go about it."
School term times are set to change in Nottingham from September next year.
There will be a two-week break in October, a fixed break at the end of the spring term and a summer holiday of five weeks, rather than six.
It is the latter which has caused the most consternation among unions.
Initially, the city council had wanted to split the school year into five equal terms in a bid to raise standards. After the strikes, negotiations between unions and council chiefs followed, eventually leading to the authority's alternative proposal, which was approved by councillors in November.
Since that decision, the unions have been discussing what steps to take behind closed doors.
The NUT revealed that a survey of its members showed that the majority were against the changes and were prepared to go on strike again.
Mr Stevenson hopes there is a chance the council might still make a full U-turn.
He added: "We are against this move. It is the wrong move.
"We are looking to continue our opposition to what we think are proposals that no one wants.
"The council changed its mind on the five-term year but seems to have been concentrating on saving face rather than doing the right thing."
The city council says that changing term times will improve attainment in the city, which has been low for many years.
Councillor David Mellen, portfolio holder for children's services, says the move is based on research.
One of the council's main arguments has been that the traditional six-week summer break is too long and leads to children forgetting what they have learned.
Mr Mellen said: "Research has told us that the six-week summer holiday can be a difficulty for some children.
"My experience as a head teacher in the city has shown me that where there is not a lot of money in a family to go on holidays or trips, at the end of the summer holiday children may not be in the same place with their learning in September as they were in July."
