From the Lawrence Daily Journal-World for March 4, 1972:

Sabbatical criteria were being considered for review at Kansas University. A ceiling was currently in place limiting the number of faculty who could be absent from campus during the year. Faculty were dissatisfied with the “seeming lack of definitive selection criteria” at the university. They were also displeased at the so-called “alimony clause” of the regents’ policy, which required those taking sabbaticals to sign an agreement to return to KU for at least two years immediately following their leave. Failure to do so required repayment to the university of a proportion of the amount paid during sabbatical.
