The most recent example: Employer reneged on negotiated clauses, citing budget cuts - what can I do?
The correct answer to most variants of this question is essentially "you screwed up by not getting it in writing, make sure you don't make the same mistake next time" - maybe with a bit of advice about lawyers, and/or finding another job ASAP, and/or the consequences of breakdown of relationship with said company. But ultimately there is generally not much the asker can do but take their lumps and learn from the sorry experience.
Given this, it doesn't seem to me that there's much value in having this type of question asked over and over again, because all it will do is attract similar answers. Which in my mind, makes it a perfect candidate for a canonical question as a dupe-close target.
