Career
Liinamaa, a lawyer specialising in labour law, began his career working for the Finnish Central Union of Trade Unions (SAK). In 1958, at only age 29, he became the town manager of Mänttä, an industrial municipality in Western Finland. Upon the creation of a nationwide labour dispute conciliation mechanism in the early 1960s, Liinamaa was appointed a regional labour dispute conciliator.
In 1965 he became the National Labour Dispute Conciliator and held the post in 1965–1970 and 1979–1980.
In 1965–1967 due to turbulent economic winds, Liinamaa was faced with conciling dozens of labour disputes. In his capacity as the National Conciliator of Finland, he was able to prevent several major strikes.
In 1967 Liinamaa was given a special task by Prime Minister Rafael Paasio: Liinamaa was to negotiate a comprehensive economical deal with employers" organisations and labour unions in order to prevent inflation due to rising wages. These negotiations resulted in the first Comprehensive Income Policy Agreement and brought fame to Liinamaa.
President Urho Kekkonen appointed a caretaker cabinet headed by Teuvo Aura.
Under Prime Minister Aura, Liinamaa served as the Justice Minister for 63 days in May–July 1970 until a new coalition government was formed by Ahti Karjalainen.

President Kekkonen appointed Keijo Liinamaa Prime Minister of a caretaker government that lasted from June to November 1975.
