But the strike did not spread to the other unions, and the Washington Building and Construction Trades Council and D.C. Commissioner George E. Allen attempted to mediate an end to the strike. The carpenters rejected the arbitration attempt, and bands of roving picketers moving among construction sites led to traffic tie-ups, frightened citizens, and rumors of violence. The "open shop strike" ended on June 20, 1934, when the carpenters agreed to a new contract providing for a five-day, 40-hour work week and $1.25 an hour in pay. But no agreement was made regarding the open shop. The plasterers' union ended their strike in June 1934, and went to local district court to resolve the jurisdictional dispute. The final labor dispute to affect the Federal Triangle complex construction was a jurisdictional strike over the installation of library shelving at the National Archives building in November 1935. The continuing existence of the District Building, Old Post Office Pavilion, and Southern Railway building as well as parking issues became points of contention during Federal Triangle's first 50 years. District of Columbia officials said in 1958 that they were willing to have the District Building torn down and Federal Triangle "finished" (if the city was properly compensated), but a lack of federal funds defeated the move. In 1995, the D.C. and federal governments signed an agreement in which the federal government would construct a new top floor and renovate the building (at a cost of $47 million) in return for a 20-year lease on 130,000 square feet (12,090 square metres) of space in the structure. Plans were developed in 1970 to demolish most of the Old Post Office Pavilion (leaving only the bell tower). But opposition to the plan emerged, and the following year plans were made to restore the building instead. In 1973, the General Services Administration (GSA) developed a plan save the Old Post Office Pavilion, and the National Capitol Planning Commission agreed to the project. An $18 million renovation began in 1977. The renovation was completed in 1983 to highly positive reviews. In the late 1980s, plans were laid to double the size of the Old Post Office Pavilion's retail space to 75,000 square feet (6,975 square metres) in order to attract more shoppers to the building. Utilizing the provisions of the "Public Buildings Cooperative Use Act of 1976", the retail space expansion was financed and completed in 1992. Despite the federal government's intention to demolish the Southern Railway Building and construct a federal office building on the site to complete the Federal Triangle complex, the building stood until 1971.
