I work about 34 miles from home and can't go check on Maggie during the day either. My compromise is doggie day care on T/W/T so she's only by herself all day Mondays and half days on Fridays. But I know not everyone can afford that - I don't have kids so this is my equivalent
I didn't crate train Maggie and while she hasn't potty trained as fast as those puppies that are crate-trained, she's learning and I believe in the last 2 weeks she's finally got it down

But then, the messes don't really bother me - she's too cute to even frown at!!
