Can you provide a specific fairly objective definition of what a "crappy" job is? Is it just a job you don't like doing? How does adding UBI address bargaining power beyond a temporary fix? Eventually prices will adjust to take into account the buying power of UBI. UBI will become the new baseline and people on UBI will lose the benefits of that buying power. Not denying that UBI won't provide a temporary fix, but there is nothing about UBI prevents the market from adjusting to take into account UBI.
