I do not advise crate training methods. If you do that sort of method, crating a dog is only to be done for a couple of hours at a time not for many hours or all day. I don't know how long she is crated while you are at work but it is likely it is way too long.
I much prefer, if you don't want your dog loose in the house, putting it in a xpen or at least barricade into a kitchen or where ever there is linoleum flooring and easy to clean. Be sure it is safe, no electrical cords to chew or anything else she could get into.
I always recommend leaving food, water, toys, and a wee wee pad or paper down. I can't imagine what it is like being in a crate for many hours day after day, where a dog cannot play, is expected to 'hold it' and sits there until the owner shows up again.
As it was once put years ago by someone else, 'how would you like to be locked out of the bathroom for 8 or 9 hours'.
Trying to get your dog to wait is not good for the dog. If they do get into waiting you could very easily set them up for bladder infections, and baldder stones.
