Chicago Board of Election workers should not be barred from unionizing, judge finds – Chicago Tribune/Yahoo

The case is just one example of the fickle nature of public sector labor law in Illinois, where legal precedent regarding which workers are permitted to form unions and which are not can vary even within the same workplace. Cook County assistant public defenders, for instance, have been unionized since the mid-1980s. Across the courtroom, however, county prosecutors are facing decades-old state Supreme Court precedent that threatens to block their efforts to unionize.
