The IRS employees who are responsible for enforcing Obamacare don't want to be in the program

Might the agency responsible for enforcing Obamacare know something about the problems with the program?  From the Washington Examiner:

National Taxpayer Employee Union officials are urging members to write their congressional representatives in opposition to receiving coverage through President Obama’s health care law.
The union leaders are providing members with a form letter to send to the congressmen that says “I am very concerned about legislation that has been introduced by Congressman Dave Camp to push federal employees out of the Federal Employees Health Benefits Program and into the insurance exchanges established under the Affordable Care Act.”
The NTEU represents 150,000 federal employees overall, including most of the nearly 100,000 IRS workers.
Like most other federal workers, IRS employees currently get their health insurance through the Federal Employees Health Benefits Program, which also covers members of Congress. . . .
