My suggestion is quite simple, show the Max daily salary someone can get for a certain job. Why?
For employees, it would be easier to find a job where you can use all the tickets you gain with houses. And for employers it would be easier to get these people.
Imagine a situation like this, made with my awesome photoshop skills:
I would rather pick the job where I can work 3 times for a little less, than the one I can work just once, and I would know that without having to pick and quit the job right after.
From a programmer point of view, that would be pretty easy to do, cause you already have a variable with the "daily max salary value", the only thing you need to do is show it.
