Mr Holyman, a technology teacher at Hummersknott school, Darlington, Derek Ward, head of ICT, Isabel Watkin, head of biology, and John Bowes, head of technology, are in their 50s.
All voted to strike on their National Union of Teachers' ballot forms, though the action has now been called off (see above). "We can retire at 60, but this is worth losing money for because it is the right thing to do," said Mr Holyman. "Teaching is a young person's profession now. Pupils increasingly do not want to listen to you.
"The young teachers can get more from the pupils. So we are prepared to go on strike for them."
Mr Holyman, who is the language college's NUT representative, will have left teaching by 2013 when the proposed new retirement age comes in.
"Changing the pension age is going to be unfair on others," he said. "I do not know anyone who is happy about it. It is wrong."
Tracey Windle, a special-needs nursery nurse, would strike over pension reforms - and is confident that parents and her headteacher would back her.
Miss Windle, who works five half-days a week at Hedworthfield primary in Jarrow, South Tyneside, said: "I am only 32, so I have a long way to go in my career but I feel very hostile about this.
"The Government could change the pension age again. Am I going to end up working until I am 75?"
Miss Windle, who has been a nursery nurse for 14 years, is membership officer for South Tyneside local government branch of Unison.
"Going out on strike is a last resort, but I am horrified that the Government thinks it can change the retirement age."
"We do a hard job looking after children. It is very stressful working in a class of 30. One of the few perks was being able to retire at 60. Teachers and support staff are going to be ill if they are forced to work until 65."
Miss Windle is sure she has the support of Teresa Lawton, Hedworthfield headteacher, and parents whose children would be affected by a strike.
Angela Wells believes that government plans to make her work till she is 65 will cost her tens of thousands.
The 28-year-old teacher at Duncombe primary, Islington, where 12 of the 15 teachers are in their 20s or early 30s, said: "I can't believe it. Young teachers are going to be especially hard-hit." The Year 3 teacher has two management points for science and humanities, and has seen her salary increase from pound;18,000 to pound;31,000 since she began teaching four years ago.
