The SOBSI chairman Harjono and Sarbupri (estate workers union, the largest SOBSI union) chairman Maruto Darusman were imprisoned after the uprising and were killed by the Indonesian army in December 1948, as Dutch troops approached the prison site. SOBSI operations were shut down by the army. Nineteen out of 34 affiliated unions withdrew from SOBSI in protest against the role played by communist leaders in the rebellion. SOBSI was however not formally outlawed, as the organization as such had not supported the uprising.Hindley, Donald.

Re-establishment

SOBSI was re-established in September 1949. The new leadership was clearly dominated by the Communist Party. The acting chairman of SOBSI, Asrarudin, left the organization in protest against the communist dominance. In November 1949, SOBSI launched a campaign against the Round Table Conference agreement. The organization also called for a

Notably, whilst no longer holding monopoly over the trade union sector, SOBSI was far better organized and financed than its rivals. Moreover, the SOBSI leadership had more experience than that of other unions. Non-SOBSI unions tended to have either a defensive approach towards SOBSI or merely mimicking SOBSI discourse.


Militant period

Between 1950 and early 1952, SOBSI attempted to mobilize militant actions, raising issues such as wages, social security and workplace conditions. SOBSI launched a wave of strikes in late 1950. In September 1950 Sarbupri launched a nationwide strike, which paralyzed most estates. The Sarbupri strike resulted in the first major victory for SOBSI, having forced the government to significantly increase the estate workers' minimum wage. Strikes by oil workers in the same year blocked plans for lay-offs and forces the government to institute a non-contributory pension scheme instead.Hindley, Donald.

In August 1951 around 3,000 SOBSI activists and leaders were imprisoned in a government crackdown on opposition, in the wake of speculations about a possible leftist coup d'état. However, relatively few SOBSI branches and unions mobilized protests against the arrests.


National United Front line

On March 1, 1952, the PKI Central Committee adopted a resolution labelling the activities of SOBSI as 'sectarian'. The PKI instructed SOBSI to align with the national

From this point onwards, SOBSI was cautious of entering into direct conflicts with the government and national capitalists. In direct contradiction to its earlier line, SOBSI even pledged to help national capitalists and to increase productivity in industries. However, the Communist Party eventually intervened against the notion of productivity-increase at its 1956 congress.Hindley, Donald.

In September 1953 a Sarbupri strike forced the government to increase wages for estate workers by 30%. SOBSI held its second national congress in January 1955. At this point, the organization had 128 branch offices and claimed a membership of 2,661,970. The congress ratified the new constitution adopted in 1952.

increasingly came to rely on SOBSI as the representative of labour. SOBSI was awarded status as a 'functional group' with representation at different levels. When Sukarno appointed a 45-member National Council on July 12, 1957, with the task of assisting the cabinet, SOBSI was awarded one seat (represented by Munir). In July 1957, the SOBSI headquarters were attacked with grenades. In September 1957 a reorganization took place inside SOBSI. The vertical and local unions were reorganized into 31 national unions. The organization had eight regional offices and 150 branches by this point. SOBSI led struggles, both in the streets and inside parliament, demanding nationalizations of Dutch enterprises. When the Indonesian government nationalized Dutch companies in December 1957, SOBSI declared its willingness to keep the companies running. In the wake of the nationalizations, inter-island shipping services were disrupted and thousands of seamen and harbour workers were left unemployed. SOBSI demanded that government pay wages to these groups, a demand conceded to by the government as it accepted to pay wages to the unemployed seamen and harbour workers until mid-1959.Hindley, Donald.

Conflict with the army

Eventually, the nationalizations resulted in increased antagonism between SOBSI and the army. In many instances Dutch-owned properties had been seized by SOBSI unions, but were later taken over by the military. Many high-ranking officers were included in the management boards of nationalized companies, and were hostile to the SOBSI influence in the state enterprises.Nyman, Mikaela.

On January 1, 1961 SOBSI declared an ambitious three-year plan of action on organizing, education and culture.

monthly publication called ''Indonesian Trade Union News''. SOBSI publications were, however, largely unprofitable. As of 1957, ''Bendera Buruh'' sales only compensated around 40% of its production costs. As of May 1957, circulation of ''Bendera Buruh'' stood at a meagre 5,500.

''Bendera Buruh'' was closed down in October 1960.Hindley, Donald.
