One pain point that should be solved is this; changing jobs is expensive, or risky. If you don't time your notice period correctly you can end up having to last on a short salary. I know a few people who got into debt in this way.

I recently had to think about this and for me, moving roles is worth probably about ~£2K salary in "life admin" (i.e. if the new role is not offer two grand more then it's not worth moving, from a purely financial motivation)
