It all comes down to if you would rather be unemployed? - I don't know, but you don't sound like you enjoy it much. If people settle, it's their problem - do you think you would do the same?
How would I deal with going to interviews if I work and it's impossible to change shifts? Sounds like a trouble for me.
It's also pretty hard to settle with selling shoes in a store after studying so much for 4 years
