Arthur Weasley didn't think he could bear to do any job other than his own. He was not someone who flourished in a professional environment or felt validated by staring crisis in the face. He was a family man with a sense of humor, and he needed a job like his, which mostly dealt in high-jinx and interactions with Muggle things that, to him, were foreign and interesting.
And even that sometimes was too much.
When he was simply studying Muggle technology to keep the Ministry informed, he loved his job. There were published authors who did not take the joy in their writing that Arthur Weasley did when asked for a report about Muggle culture.
And Muggle-baiting, well, he could handle that. Mostly. He forced himself to create distance when he could, to try and think of the incidents like the pranks that he secretly enjoyed Fred and George playing on everyone. But the truth of the matter was always there. It was in every case that landed on his desk, no matter how small. No matter how he framed it, no matter what the Ministry called it, no matter what was written on the office door, Arthur was in charge of hate crimes. Day in and day out. He watched how wizards, some his own colleagues, treated muggles for no reason other than them not having magic. He watched the offenders go free most of the time, and he could never apologize to the muggles, because if they'd caught on to magic, their memories would be wiped anyway.
His gigantic battle from the Ministry's smallest office.
So Arthur counted on the wins. Because sometimes the offender was indicted. And sometimes a tragedy in either community- magical or muggle- would prompt a month with a lot fewer incidents, a quiet respect. And very occasionally, if a wizard caught a muggle-baiter in the act, he or she would come to the muggle's defence. In terms of paperwork, this was a nightmare as it usually meant more memories to erase, but Arthur never slept better than he did on those nights.
Yes, there was a vague misery about being in charge of Misuse of Muggle Artifacts in a world that still for the most part quietly hated muggles. But Arthur had family, and friends, and enough experience to see the good in people. For him, that was enough.
