I have absolutely no idea why you would think tech workers are immune to layoffs or that the tech industry is somehow not affected by general global market conditions.

They are capitalist for profit enterprises in a largely globalized and largely capitalist world, and the easiest thing to do to keep nearly any large company profitable in a general downturn is to lay off employees.

Sorry that you too are personally affected by the inexorable logic of the system by which nearly all economic production of nearly all kinds for nearly the entire world operates by, I guess?
