It all depends on everything else in your life - can you afford to live without work for a while? If you are in the USA, do you need health coverage through your work, or do you have other options? Do you have any discussion going on with people to make a move or are you starting from scratch seeking work and having to send in resumes?

In general, I stay only as long as my circumstances force me to stay. At the same time, there are ways to make a soul sucking job suck less - mostly by figuring out how to do the job without caring about the job. Be that burned out cynical co-worker who just scrapes by and doesn't truly care. It is a bad attitude for building a career with a company, but a life-saving attitude if your current employer will never take care of your needs anyway.
