In 1951, in response to a growing number of families moving to the suburbs, LIU purchased an 177-acre (72 ha) estate known as Hillwood from cereal heiress Marjorie Merriweather Post and her third husband Joseph E.

[10] Cline outsourced the work of two groups of previously unionized workers on campus, and oversaw the lockout of 400 faculty on the day prior to the beginning of the 2016–17 school year.

[13] This is the first time that a college or university in the United States has used a lockout against its faculty members, according to William A. Herbert, executive director of the National Center for the Study of Collective Bargaining in Higher Education and the Professions.

[15] In the first week of the autumn term, some students at LIU Brooklyn staged a walkout in support of the locked-out teaching staff.

[16] With the 236 full-time faculty members and 450 adjuncts locked out, classes were taught by university administrators and temporary staff, and students reported inadequate instruction.
