The tech giants negotiations are relying on the monopoly that the state provides. Just to pick one piece of legislation, the 1947 Taft-Hartley Act, the government disallows various worker/employer agreements that benefit those doing the work. Meaning corporate America generally outlawed certain deals that could happen, when the workers were in a good position, that the corporation was willing to do. That is relying on the monopoly the state provides.
The Taft-Hartley act also bans secondary strikes, so unions are further restricted (this restriction was increased more with the Labor Management Reporting and Disclosure Act in 1959).
The Taft-Hartley act also allowed the president to ban strikes in the case of a "national emergency". Of course, national emergencies were seen all over the place since then, including in 2002 on the west coast docks with the ILWU.
There are the people doing all the work and creating all the wealth, then there are the heirs and such who feed off their expropriation of the surplus labor time of those doing all the work. The idle class relies on the monopoly that the state provides.
In fact, if you look to history and the creation of the first states in Sumeria thousands of years ago, the raison d'etre of those states were to use violence and propaganda so that an idle class could expropriate surplus labor time from their slaves doing all the work.
