Albertson's,Safeway, Yokes(which is just in washington), even Kmart offers health care to full time employees. Kmart being the only one that doesn't offer full health care anymore since they do not have the money.Most other retailers and grocery stores don't offer full health care, why should Walmart? Just because they can afford it? They do pay for 2/3 of the premiums.
Just face it. Walmart hires unskilled workers to do easy jobs. If someone wants to make a lifelong career out of working customer service at Walmart, they know what they are getting themselves into. If they want more money or better benefits, there are other jobs out there.
