Many SO's are independently operated and aren't unionized. I've been to both kinds over the years and they range from "thumbs in ass 6 mile long line with 1 wicket open" to "well oiled machine". Management seems to have more of an effect on that vs anything else.
Has there been any announcement on which ones are being closed? Are they conveniently the remaining government operated unionized ones, or any privately operated ones? I'm wondering if there is any rhyme or reason to the decisions, based on satisfaction numbers or anything meaningful, or whether some Ford bureaucrat basically went Eenie Meeny Miny Moe, or decided based on what Staples (*cough*) wanted?
