ALWAYS WORKING

My husband is always working and when he is at home he doesn't spend a lot of time with the kids. He complains about being tired but i run a household and work part time and still manage myself. I try to get him involved with his family but he keeps on giving excuses about being too tired and he would rather spend his time at home. The kids get frustrated because they have been waiting for their dad to come home. I'm frustrated with the same routine over and over again and again. What should I do ?
