The air was already full of pollen when grasses released another fusillade that peaked in June. Next up, ragweed.

The result can be a tremendous drag on the workplace, with more and more employees reeling from allergy-related respiratory problems and headaches, leaving work early or being less productive. Ditto for students in schools.
