2005, the Public Service Association of New South Wales and the Community and Public Sector Union were in dispute with the university over a proposal to privatise security at the main campus (and the Cumberland campus). In February 2007, the university agreed to acquire a portion of the land granted to St John's College (a residential college of the university) to develop the Sydney Institute of Health and Medical Research, now the Charles Perkins Centre, named in honour of the first Indigenous Australian man to graduate from the university, Charles Perkins. 2010s In 2010, the university received a Pablo Picasso painting from the private collection of an anonymous donor. The painting, Jeune Fille Endormie, which had not been publicly seen since 1939, depicts the artist's lover, Marie-Thérèse Walter and was donated on the strict understanding that it would be sold and the proceeds directed to medical research. In June 2011, the painting was auctioned at Christie's in London and sold for £13.5 million ($20.6 million AUD). The proceeds of the sale funded the establishment of many endowed professorial chairs at the Charles Perkins Centre, where a room dedicated to the painting, now exists. At the start of 2010, the university controversially adopted a new logo. It retains the same university arms, however it takes on a more modern look. There have been stylistic changes, the main one being the coat of arm's mantling, the shape of the escutcheon (shield), the removal of the motto scroll, and also others more subtle within the arms itself, such as the mane and fur of the lion, the number of lines in the open book and the colouration. The original Coat of Arms from 1857 continues to be used for ceremonial and other formal purposes, such as on testamurs. Action initiated by then-Vice Chancellor Michael Spence to improve the financial sustainability of the university caused controversy among some students and staff. In 2012, Spence led efforts to cut the university's expenditure to address the financial impact of a slowdown in international student enrolments across Australia. This included redundancies of a number of university staff and faculty, though some at the university argued that the institution should have cut back on building programs instead. Critics argued the push for savings was driven by managerial incompetence and indifference, fuelling industrial action during a round of enterprise bargaining in 2013 that also reflected widespread concerns about public
