If I miss Mass for no good reason, may I receive Communion when I do go, even if I didn't get to confession?
No, you ought to first go to confession. The Catechism, in conformity with ancient teaching about the necessity of attending Mass says, “Those who deliberately fail in this obligation commit grave sin.” (#2181). Hence you ought to go to confession first. There are some reasons that one might miss Mass that are legitimate such as serious illness, the care of the sick, or some lack of capacity due to weather or distance. So also struggle with work schedules. But in this matter they should consult with their pastor or confessor and also seek solutions.
