Having been involved finances at a multi-national, i doubt this works.
Each country is it’s own free standing company with it’s own P&L. And combined profit is what rolls up into annual reports.
I highly doubt a company like Google would let a country ride with poor profit dragging down earnings per share.
And on top, they arent going to risk US revenue (likely several multiples of most countries in Europe) by firing people they actually need just to avoid laying people off in another country.
It’s cheaper to just do the bare minimum of whatever the country requires for lay offs and be more careful hiring next time to avoid layoffs in the future.
