Washington Post Federal Diary columnist Joe Davidson today looks at the question of who at the Internal Revenue Service might take the blame for the agency’s targeting of Tea Party groups. One group that isn’t talking? The union that represents those workers:

In cases like these, there’s often the suspicion that front-line or lower-level workers will be forced to take the fall for higher-ups. Labor organizations can play an important role in protecting employees from being unfairly disciplined while management slides.

So far, the National Treasury Employees Union, which generally is not shy with public comment, has next to nothing to say about that or anything else.

“NTEU is working to get the facts but does not have any specifics at this time. Moreover, IRS employees are not permitted to discuss taxpayer cases. We cannot comment further at this time,” NTEU President Colleen M. Kelley said via e-mail.

A call to the NTEU office in Cincinnati resulted in a similar response: “We’ve been directed by national office. We have no comment.”
