===Transition and 1980's===
Since the [[Spanish transition|democratic transition]] until 1987 its secretary general was the historic union leader [[Marcelino Camacho]], also a prominent leader of the [[Communist Party of Spain|PCE]] and [[Congreso de los Diputados|deputy]] between 1977 and 1981. In 1976 CCOO held the Assembly of Barcelona, where the modern class trade union confederation was formed. CCOO was legalized on 27 April 1977. The [[Atocha massacre|murder of 5 labor lawyers in 1977]] (members of the union and the PCE) in Madrid that year was followed by a massive funeral, more than 250,000 people participated, and the strikes that followed helped the legalization of the organization. In those years the union is growing rapidly in membership, like the rest of unions and leftist parties. From 1976 to 1978, CCOO went from 30,000 to 1,823,907 members. However, after the signing of the [[Moncloa Pacts]], this figure gradually begun to descend, passing to 702,367 in 1981 and 332,019 in 1986. This negative trend in membership started to change since 1987.<ref>{{cite web |archive-url=https://web.archive.org/web/20120412174842/http://www.ccoo.es/comunes/temp/recursos/1/155484.pdf |title=La evolución de la afiliación a CC.

In 1976 the [[Confederación de Sindicatos Unitarios de Trabajadores]] (CSUT), a group of CCOO members affiliated with the [[Party of Labour of Spain]] (PTE) split from the organization. In May 1977 CCOO suffered another split, this time from supporters of the [[Maoism|maoist]] [[Workers' Revolutionary Organisation]] (ORT), that formed the [[Sindicato Unitario]].<ref>{{cite web |last=Molina Blázquez |first=José |title=Apuntes para: orígenes y evolución de la Organización Revolucionaria de Trabajadores |date=December 2009 |url=http://ort-ujm.es/main/index.php?option=com_content&view=article&id=263&Itemid=123 |access-date=7 March 2019 |work=[[Organización Revolucionaria de Trabajadores]]-[[Unión de Juventudes Maoistas]]}}</ref>

The year after legalization in 1978, CCOO held its I Confederal Congress, where [[Marcelino Camacho]] was reelected, what would happen again in the Second (1981) and III (1984) congresses. CCOO also was the most voted union (37.8% of the representatives) in the [[Spanish trade union representative elections, 1978|workers representative elections of 1978]], the first democratic ones in the [[history of Spain]]. In this last congress, different factions emerged, including a majority linked to [[Communist Party of Spain|PCE]] (led by [[Marcelino Camacho]]) and three minorities, respectively linked to the [[Workers' Party of Spain – Communist Unity]] (PTE-UC) (called ''[[Santiago Carrillo|carrillistas]]'' and led by Julián Ariza); the [[Communist Party of the Peoples of Spain]] (PCPE); and the [[Revolutionary Communist League (Spain)|Revolutionary Communist League]] and the [[Communist Movement]] (known as ''Izquierda Sindical'').<ref>{{cite web |url=http://www.caesasociacion.org/movimiento_obrero_sindicalismo/ficheros/transicion_politica_espa%f1ola_sindicalismo_radical.pdf |title=Transición política y sindicalismo radical |work=Centro de Asesoría y Estudios Sociales |language=es |pages=6 |access-date=7 March 2019 |archive-date=16 March 2020 |archive-url=https://web.archive.org/web/20200316155052/http://www.caesasociacion.org/movimiento_obrero_sindicalismo/ficheros/transicion_politica_espa%EF%BF%BDola_sindicalismo_radical.pdf |url-status=dead }}</ref> In 1980, CCOO received an important part of the [[Unión Sindical Obrera|USO]] members, that belonged to the [[socialist self-management]] current. In 1986 the union participated in the historical mobilizations against the permanence of Spain in [[NATO]]. CCOO asked for a "NO" vote in the [[Spanish NATO membership referendum, 1986|NATO referendum]].

CCOO called 4 general strikes in the government of [[Felipe González]]: 1985, 1988, 1992 and 1994; against the economic and employment policy of the [[PSOE]] government. Especially massive and historic was the [[1988 Spanish general strike]], organized jointly with the [[Unión General de Trabajadores|UGT]], which had a 95% of following, and forced the government to totally withdraw the Youth Employment Plan.
