That process could take weeks and there are some expenses that can’t be cut (like rent). It can also take a few weeks after being approved to get the first check, and even then it might not be enough.You do what any private sector employee does, you cut expenses and file for unemployment. In short, you figure it out. The government have programs for this situation.
I also don’t see how overloading a program such as unemployment is just being casually seen as the solution to this.
