# Socialism and Man in Cuba defends unpaid voluntary labour and the 'new man' as a dated labour-ideology letter

Date: 1965

## The fact

On 12 March 1965 [Guevara](/people/che-guevara)'s letter later titled Socialism and Man in Cuba defends unpaid voluntary labour and a 'new man' as the socialist personality. The instrument is that letter, not a later poster of his face. Che Guevara's documented role is: He wrote the letter to Carlos Quijano. Factories and Saturday work were already a state practice. He is not stored as the sole inventor of unpaid overtime.

## Context

Marcha in Montevideo is the named carrier. Sharing factory Saturday work with the Cuban state is required. Literacy brigades remain a separate cohesion row. The setting of Socialism and Man in Cuba defends unpaid voluntary labour and the 'new man' as a dated labour-ideology letter is the public file around 1965-03-12. Shared offices, unnamed crews, printers, or later editors may appear without becoming this instrument. Driver [labour-market-tightness](/drivers/labour-market-tightness) is attached because the significance names a mechanism from this act, not because a standing list needed coverage.

## Significance

Worsening path from Socialism and Man in Cuba defends unpaid voluntary labour and the 'new man' as a dated labour-ideology letter on 1965-03-12. A public defence of unpaid labour as civic virtue is a labour-market path stored as cost: tightness here means coerced extra hours, not a wage series. The welfare reading on this path is worsening.

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.
