In industrial economics and employment sociology, the two primary categories of labor are skilled labor (requiring specialized training, education, or technical expertise, such as engineering, medicine, or carpentry) and unskilled labor (requiring minimal specialized training, focusing primarily on manual tasks). In the medical and obstetric context, the two main phases of childbirth are true labor (characterized by progressive, regular, cervical-dilating uterine contractions) and false labor (Braxton Hicks contractions that do not progress).
