walmart
Updating my last post.......
I did some research and yes Walmart is an ERISA heath plan.
They used ERISA to defend the recent MD court case for fair-share spending.
Here's one quote from the court findings... ERISA establishes comprehensive federal regulation of employers' provision of benefits to their employees. It does not mandate that employers provide specific employee benefits but leaves them free, "for any reason at any time, to adopt, modify, or terminate welfare plans." Curtiss-Wright Corp. v. Schoonejongen, 514 U.S. 73, 78 (1995). Instead, ERISA regulates the employee benefit plans that an employer chooses to establish, setting "various uniform standards, including rules concerning reporting, disclosure, and fiduciary responsibility." Shaw v. Delta Air Lines, Inc., 463 U.S. 85, 91 (1983).
