After winning the 1924 general election, Baldwin formed his second government, which saw important tenures of office by Sir Austen Chamberlain (Foreign Secretary), Winston Churchill (at the Exchequer) and Neville Chamberlain (Health). The latter two ministers strengthened Conservative appeal by reforms in areas formerly associated with the Liberal Party. They included industrial conciliation, unemployment insurance, a more extensive old-age pension system, slum clearance, more private housing and expansion of maternal and childcare. However, continuing sluggish economic growth and declines in mining and heavy industry weakened Baldwin's base of support and his government also saw the General Strike in 1926 and the Trade Disputes and Trade Unions Act 1927 to curb the powers of trade unions.
