In August 2013, workers at the telescope went on strike to demand better pay and working conditions. This is one of the first strikes to affect an astronomical observatory. The work stoppage began after the observatory failed to reach an agreement with the workers' union.<ref>{{cite web|url=http://almaobservatory.org/en/component/content/article/634|title=ALMA Observatory Statement|author=Alejandro Peredo|access-date=15 November 2014|url-status=dead|archive-url=https://web.archive.org/web/20141129014233/http://almaobservatory.org/en/component/content/article/634|archive-date=29 November 2014}}</ref><ref>{{cite news|url=https://www.washingtonpost.com/world/the_americas/workers-at-earths-largest-radio-telescope-in-chile-strike-over-pay-working-conditions/2013/08/22/05eb11d6-0b6e-11e3-89fe-abb4a5067014_story.html|archive-url=https://web.archive.org/web/20130823191323/http://www.washingtonpost.com/world/the_americas/workers-at-earths-largest-radio-telescope-in-chile-strike-over-pay-working-conditions/2013/08/22/05eb11d6-0b6e-11e3-89fe-abb4a5067014_story.html|url-status=dead|archive-date=23 August 2013|title=Workers at Earth's largest radio telescope in Chile strike over pay, working conditions|date=22 August 2013|newspaper=[[The Washington Post]]}}</ref><ref>{{cite news|url=https://www.bbc.com/news/av/world-latin-america-23807459/alma-telescope-crew-go-on-strike|title=Alma telescope crew go on strike|work=[[BBC News]]|access-date=15 November 2014}}</ref><ref>{{cite web|url=https://www.huffingtonpost.com/huff-wires/20130822/lt-chile-alma-observatory-strike/|title=Workers strike at world's largest radio telescope|publisher=[[Huffington Post]]|access-date=15 November 2014|archive-url=https://archive.today/20130825013249/http://www.huffingtonpost.com/huff-wires/20130822/lt-chile-alma-observatory-strike/|archive-date=25 August 2013|url-status=live}}</ref> After 17 days an agreement was reached providing for reduced schedules and higher pay for work done at high altitude.<ref>{{cite web |title=ALMA resumes operations after end of workers' strike |url=http://www.almaobservatory.org/en/press-room/announcements-events/639-alma-resumes-operations-after-end-of-workers-strike |website=almaobservatory.org |access-date=11 May 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150518095236/http://www.almaobservatory.org/en/press-room/announcements-events/639-alma-resumes-operations-after-end-of-workers-strike |archive-date=18 May 2015 }}</ref><ref>{{cite news|title=17-Day ALMA Strike Ends in Resolution|url=http://www.skyandtelescope.com/astronomy-news/17-day-alma-strike-ends-in-resolution/|website=Sky & Telescope|access-date=11 May 2015|date=2013-09-06}}</ref>
