UP SOLAIR traces its origins from the Labor Education Center (LEC) which was established in 1954, to promote social justice and labor empowerment through education, research and labor empowerment. It started as a project of the UP School of Business Administration, through its Dean Jose Valmonte in 1953 in response to the new era of collective bargaining and economic unionism with the passage of the Industrial Peace Act (RA No. 875- Magna Carta of Labor) in 1953 (Sibal, 2008). Training and professional staff including labor lawyers, researchers and trainers conducted studies, training and capacity-building programs to assist labor organizations, particularly the trade unions and cooperatives. The Center expanded its services in Asia. According to former Dean Ofreneo, this was an offshoot of the Cold War during the 1950s (Ofreneo, 2008 as cited by Sibal, 2008). The center was subsequently renamed the Asian Labor Education Center (ALEC) in 1958 and became the leading regional training institution for Asian trade union leaders.
