In the building of the former Labriadeios Housekeeping School, and current building of PALASE, is performed and hosted the Post-Graduate School from 2011, which deals with the history, the society and the labor culture. Particular attention is paid to the exploration of the changes occurring in the nature of work in modern society, changes that enhance social inequality.
