Get a different crate. Exercise and tire your dog out but you should also work on getting her to love her crate. Do you use it as punishment ever? You can try to do some crate games.
Maybe get her a nice antler or freeze some peanut butter in a Kong so it lasts longer. Toys she doesnt need supervision with. Start feeding her in her crate. You want her to associate good things with being in the crate, not just that you are leaving. Encourage her to go into the crate and get a reward throughout your time when you are home with her.
