Rift between Gov. Baker, teacher unions deepens on vaccines March 11, 2021 FacebookTwitterEmail WORCESTER, Mass. (AP) — The rift between Massachusetts Gov. Charlie Baker and the state’s teachers unions deepened Thursday as the Republican bristled at calls to take additional steps to vaccinate educators before ending virtual education in favor of in-classroom learning. On Wednesday, the administration announced that it was designating four days when the state’s seven mass vaccination sites will offer first doses only to K-12 teachers, childcare workers and K-12 school staff. The special vaccination days are March 27, April 3, April 10 and April 11. The state also announced that beginning this week, teachers are eligible to receive vaccination shots under state guidelines.
