Both the Family Medical Leave Act (FMLA) and the Oregon Family Leave Act (OFLA) to come into place require a given employer to have at a minimum 50 employees. The issues as to whether these two acts apply to you depends upon how the assorted businesses are structurally held as under one corporate entity or not from what I see. I suggest that you consult with the human resource person with your company to see if either of these acts apply to you and your pregnancy.
