|Sweatin' to the Work Week|
Lancelot, knight errant & confidant of king & queen, responded based on the chivalric code & his 'job'. Although, different writers interpret him differently from Mallory, the basis is his profession. The fool in Christopher Moore's retelling of King Lear is defined by his occupation - everything he does or doesn't do is an extension of that. Atticus, the lawyer, in 'To Kill a Mockingbird' acts from a core of lawyerly intent; his sense of fairness, right & wrong extends from this core.
From high fantasy to women's literature, the MCs profession provides clues to a deeper sense of character. Fairy duster to pencil pusher, all come with a set of characteristics; some that readers expect & some they don't.
What does the MC in your current WIP do for a living & how does that affect the story arc? The goals/motivations/conflicts? The outcome - from HEA to no HEA?
