You could suggest the IT guys try a different link standard that moves them out of the 2.45 GHz ISM band. You can also buy new microwave ovens, since publicly accessible ovens get a pretty horrible beating during use, and may be leaking from sprung doors or abused door seals. You can also get industrial microwave ovens that operate at 960 MHz. These ovens are often huge (imagine making taco filling starting with frozen slabs of beef and lard), but maybe some table models are available. (The 960 MHz penetrates food much deeper than the consumer 2450 MHz, so it lends itself to industrial cooking.)
