I don’t work at AWS bit I think youre being a bit optimistic about the level of automation most services have. If there are no SREs present for a month, things will break at even the most sophisticated tech shops.
I meant this as a commentary on the strike as a tactic for tech workers generally. SREs and Ops are the teams that seem most able to effectively use a strike to disrupt revenue, to be sure. Many services, though, would be able to operate for months or longer without intervention.
