Center opened. Named for Desmond Tutu, former visiting professor at GTS and retired archbishop of the Church of the Province of Southern Africa, the Tutu Center operates primarily as a hotel and conference center. In 2007 the seminary engaged in an effort to reduce its carbon footprint, along with general operating costs, by converting many of its buildings to geothermal heating and cooling. Also in 2007, the seminary, in need of funds, sold Sherrill Hall, a 1960s building along 9th Ave to the Brodsky Organization for the construction of a residential condominium building. The Chelsea Enclave was completed in 2010 and contains 53 residential units as well as retail space, an underground parking garage, and the seminary's new Keller Library. The seminary's main entrance is now located on 21st Street between 9th and 10th Avenues. Still facing financial difficulties, General Theological Seminary is currently engaged in its Plan to Choose Life, a strategic initiative which necessitates the sale of several properties: 422 West 20th Street, the Chelsea 2,3,4 building, and the West Building. Assets from the sales are expected to eliminate the seminary's debt, rebuild its depleted endowment, and restore it to financial solvency. 2014 In September 2014, eight of the seminary's ten full-time faculty announced their intention to unionize and announced their intention to absent themselves from teaching and worship, alleging harassment and bullying behavior on the part of Dean Kurt Dunkle. In a letter to the Board of Trustees on September 17, the eight faculty alleged that Dunkle had repeatedly made racist, sexist, and homophobic remarks; made unprofessional comments about faculty members to their colleagues; compromised the confidentiality of student records; and responded to staff who complained of his behavior by threatening their jobs. The protesting faculty warned that unless the Board agreed to meet to discuss the allegations, the eight would be obliged to absent themselves from teaching, meetings, and worship. The Board of Trustees of the seminary treated the letter as a mass resignation, which it accepted on September 29. The faculty contested this characterization, noting that no resignations were tendered, and published the details of their grievances online, including the original September 17 letter. The news quickly became a national issue widely reported on within religious circles. A previously arranged series of lectures by a visiting theologian from Duke had to be canceled when he declined to attend, citing the controversy roiling the seminary. Around
