Give her a reason to stay off the phone when she gets home. Have some nice appetizer/snacks and maybe a drink ready for her. Have her sit down and help her take her shoes off. Put your arm around her, kiss her and tell her how much you missed her or how glad you are that she is home and you can spend time together. Cook a nice dinner together sharing laughs, hugs and a glass of wine. Take her phone away and tell her tonight is your night, not the phone's. If she likes to clean up when she gets home have heated towels and scented bath salts or body wash ready for her to use. Get some bath oil she can smooth on (or you can smooth on) after the shower or bath. Help her relax and let her know you want to be with her. If she is really into you she will get the idea. If she doesn't, you're right. She is more interested in work than you.

Good luck.
