If you mean an actual working hour, it's really not that bad. Running through all the 30m faucets is around a minute of time, so you can do that 60x in a working hour.

I'd suggest doing it passively. Ex. I run through them while watching TV and such, since it's downtime regardless.

It's definitely not a get rich quick scheme, but think about it like this: any BTC's you earn are going towards the 21 million maximum (I think it's 21m?), so they will likely increase in value later, especially with how the news has been going.
