You could do something to try to prove your point (about damage because of high temperature).
  Take one bottle of hematoxylin to your house (that I assume is at "good" temp.) this Friday.
  Come Monday cut an extra set of slides and stain one set with the hematoxylin left in the lab without A/C during the whole weekend, and another set with the hematoxylin you took to your house.
  Compare them and decide who is right about this issue.
