Walmart is significantly rolling back health care coverage for part-time workers while raising premiums for many full-time employees. All future staff who work less than an average of 24 hours per week will no longer qualify for any of the company’s health insurance plans.

Additionally, new workers who average 24 to 33 hours per week will no longer be able to include a spouse as part of their health care plan. Walmart cited rising costs as the reason for the change. The move is a major shift from a few years ago when the grocery retailer extended coverage for employees and their families after facing criticism because many workers could not afford, or did not qualify, for coverage.
