In an e-mail to all faculty and staff Monday, Vice President for Human Resources Michael Peel announced several changes to the University’s workplace violence policy designed to enhance security at Yale. The updates follow a Sept. 30 message in which University President Richard Levin announced administrators were reviewing security policies, partly in response to the murder of Annie Le GRD ’13.

In addition to requiring all employees to report such behavior to authorities or supervisors, the document now spells out what constitutes “prohibited behavior,” including physical violence, intimidation, threats, harassment and arson. Starting Jan. 1, 2010, casual staff, postdoctoral associates and staff hired by vendors — in addition to full-time employees — will undergo background checks. And though weapons were previously prohibited by the University, the workplace violence policy now includes a section specifically about the ban.

In his message, Peel also reminded faculty and staff that they can send security suggestions to a newly created e-mail address, security.suggestions@yale.edu.
