Teachers urging colleagues to vote in favour of a pay strike should be aware that there is a sweeter, more romantic alternative.
Just copy the strategy of staff at schools in the US town of Lanesborough, Massachusetts. They sent Valentine's cards to the chairman of their local school committee to express their upset at negotiations over their contracts.
The 19 messages sent to Richard Cohen included poems such as "Roses are redTeachers are bluePlease settle the contractThe time is due" and the slogans "Have a heart, settle the contract" and "Happiness is ... a fair contract".
Unfortunately, Mr Cohen was not touched by the messages, labelling them "intimidating and abusive". Because, obviously, there's nothing more intimidating than receiving a card showing a bunny rabbit holding some flowers. Several of the town's residents seemed to agree that the stunt was inappropriate. Last week, one of them wrote a stern letter to the local paper the Berkshire Eagle Staff, saying: "One might accept this type of ill-conceived prank from college kids, but from 'educated' teachers, many of whom make more than $70,000 (pound;35,000) a year for 180 days of teaching, it's outrageous."
