March 4th, 2012- Princeton University has joined other Ivy League brethren in opting not to invest new funds created by HEI Hospitality, a Norwalk-based hotel investment firm that's been accused of unfair labor practices.

Yale University announced in November that it will not make new investments in the company, joining Brown University and University of Pennsylvania, after hearing complaints from hospitality workers, alleging that HEI condones unfair work practices at some of its hotels.
