June 18, 2012: As cities and states across the nation take aim at public employee pensions, Boston City Hall is engaged in a very different debate: how much to increase retirees’ checks.
Mayor Thomas M. Menino is proposing to boost the annual cost-of-living adjustment for most pensioners from $360 to $390, a $30 increase. City Council president Stephen J. Murphy is pushing for more, seeking a $90 increase over the current rate.
