I also take it to mean that it's either work others are often unwilling to do, or something that's really difficult, or something that I've been wanting for a long time but haven't gotten anyone to help me with.

For example: There's a fluorescent light above my desk that flickers and has been driving me crazy for years. I can't get facilities to fix it because they need a ticket that's approved by management and has an approved budget, and all their other tasks are more urgent.... so it slowly drives me mad for a year. Finally, a facilities person says "You know what... I'm not supposed to do this without management approval... but I'll just fix this real quick and it'll be our secret" ..... Me: "Oh, thank you, you're doing God's work"
