Diana Isom wants a good job that allows her to do more than get by, but the systems around her make that hard. The better-paying jobs she sees on job boards have long hours and unpredictable schedules. She’s lost one job already because her son got sick. Some of the more affordable daycare options she’s found don’t provide care beyond 2 p.m. And as a single mom without health benefits, she is worried about taking her 2-year-old to the doctor because the expense just might wipe out the little she has been able to save.
