KANSAS CITY, Kan. (AP) Many department chairs at the University of Kansas are pushing back against the school’s plan to have classroom instruction in the fall, saying they should have the option to teach online.

On Monday, a letter signed by 38 department signed heads was emailed to Provost Barbara Bichelmeyer after Chancellor Douglas Girod announced last week that the school would hold in-class sessions starting Aug. 24. KCUR-FM reported Thursday that another 14 have signed since then.

Instructors can ask for an exemption from the requirement under the Americans with Disabilities Act, which department heads call “impossibly unwieldy, discriminatory and perhaps illegal.”
