Jobs in retail, manual labor and construction, cosmetology, writing and the food industry are typically available to people without a high school diploma. These jobs require relatively little skill, and the employer may feel that on-the-job training provides sufficient skills for new employees to carry out their duties effectively.
Good communication skills are typically desirable in jobs that don't require high school diplomas. While jobs in the retail and customer service sectors may not require degrees, employees need to be respectful and agreeable to clients. Jobs in construction require physically fit employees who follow instructions well. Working in the food industry as a cook, dishwasher or waiter also requires good people skills and attention to detail.
