NEW YORK (AP) — Sniffling, groggy and afraid she had caught the flu, Diana Zavala dragged herself in to work anyway for a day she felt she couldn't afford to miss.

A school speech therapist who works as an independent contractor, she doesn't have paid sick days. So the mother of two reported to work and hoped for the best — and was aching, shivering and coughing by the end of the day. She stayed home the next day, then loaded up on medicine and returned to work.

"It's a balancing act" between physical health and financial well-being, she said.
