MAPA had done everything possible to delay the negotiations and thus frustrate the members. But they could never avoid negotiating with the staff union. The first collective agreement was signed on February 26, 1951 between the All Malayan Staff Union Real Estate Federation and MPIEA. The second cost-of-living agreement was signed on December 22, 1955. All this was between 1951 and 1958 August 1956 the Federation was unionized and registered as the All Malayan Estates Staff Union (AMESU). AmESU then took the dispute over the salary increase through the constitutional and legal procedure in an attempt to reach a settlement of their claim with employers. In August 1957, after the failure of the negotiation of the agreement following the Industrial Courts Ordinance of 1948, both AMESU and MPIEA were referred as a contentious point before the Commissioner of Labour Relations. With submission to this process, the union is at a disadvantage.
However, the 1951 agreement was replaced by the MPIEA/AMESU agreement, signed on 29 December 1958. This agreement was for two years. The following three agreements were signed in 1962, 1965 and 1971. The 1971 agreement was replaced by an employment tribunal price of 120/78, promulgated by the industrial court after 4 years and 8 months of struggle. Since 1948, each negotiation with MPIEA and its successor MAPA has taken several years to reach an agreement. The agreements contained only provisions relating to salary, qualification allowance, annual leave, bonuses, hospital services, reduction services and fuel and water supply. No agreement can be vague and ambiguous than the one signed between 1951 and 1971. Plantation employers were responsible for the delay in the 1974 negotiations by accusing the union of its inappropriate claims and management`s inconsistent attitude.
