There is a tine to speak up. at meals with close family. At meetings with your boss. The right question at company meetings - though there are wrong question here: think long and hard before ask.

You can speak up it meetings with your team but be careful of the tone. You need to come off as overall having the companies back but this one thing you can't support. Or maybe things will change again. There are lots of options.

There have been recessions before. There will be a recovery. Leave when things get better (or you retire) and cite working conditions in the bad times in your exit interview.

unions can work, but they can force you into situation you don't want to be in.

As a collective we would have done well to have organized long ago. Unions or professional associations with teeth (e.g. like the Bar for lawyers, CPA boards for accountants etc) seem to be the only realistic options
