I work full time from 8am-5pm (with Sunday and Monday off) and MY dog is crated whenever I am not home. I live about a five minute walk from my work, so I can easily come home on my lunch hour to take your pup for a walk if needed :) I don't had additional crates; but you're welcome to bring your own - otherwise the dog will likely be kept in my bathroom (open window for air, with a comfortable blanket) unless they're absolutely not going to have accidents while I'm gone.
