Lecturers' union Natfhe may join other trade unions in a mass one-day strike over government plans to raise the normal pension age from 60 to 65. Natfhe is to ballot its 65,000 members recommending they take strike action, likely to be on April 14, in protest against a move the union believes will worsen the pensions of thousands of lecturers in the Teachers' Pension Scheme. The change will affect all new entrants to the profession from 2006.
