>What would happen if you all called in sick?

Probably a government lawsuit on the employees to investigate the suspicious mass sick leave, and on the doctors who issues the sick leave notices.

And during discovery they would uncover the written paper trail employees used to organize the mass sick leave and then they'd get sued for sabotage and have to pay damages to the employer.

That wouldn't fly over here, since that would be considered intentional sabotage which is not legally allowed by law here, and heavily punished with fines or jail time. The only legal outlet for labor protests is conversations and negotiations through unions, which are toothless and more for show, to give the workers the impression that their opinion matters and they're not under the boot of government and corporations.

Austria isn't as friendly to labor uprising as modern US due to the very strict laws and legal system that restrict what workers are allowed to do against their employers, there's no "jury of your peers" to let you off the hook if you damage your employer's business in protest. Everything is done for "stability" including defanging labor powers.
