Sir, - Congratulations to our teachers' union! By threatening to sabotage the Young Scientists competition, one of the most progressive developments promoting scientific education in Ireland, a showpiece attracting industry and great fun for all concerned, it has shown the worst characteristics of destructive abuse of trade union power. Naturally the sponsors will be very reluctant to recognise unions inside their firm if this is how an Irish trade union attacks the interests of children and outside firms. - Yours, etc., Louis Smith,
The Elms, Donnybrook, Dublin 4.
