Some specialty workers prepare food for sale in the grocery store but work in kitchens that may not be located in the store. Bakers produce breads, rolls, cakes, cookies, and other baked goods. Because of the expansion of the industry to meet the consumers’ desire for “one-stop shopping,” grocery stores have begun to employ an array of workers to help meet that need.
Bakers can attend training courses provided by trade schools and industry associations, but they can also learn the necessary skills on the job.
