The multiple mentions of Pittsburgh are a bit incidential to the story there. They mention how the local AAA offices could not get their employees to work in February and had to rely on outsourced services from companies pooling lots of stay at home workers armed with their phones and computers. I think homesourcing might be a better description of what they are talking about.
But even if the focus on Pittsburgh is incidential to the story it is not incidential to us. February had all sort of labor force issues here in town. If established firms could not get their workers to their job sites because of weather, I bet an awful lot of routine hiring was deferred at the very least. AAA was even one of those places that I think would be needed a lot more during a snow storm than at other times.
Thus... when you look at February's unemployemnt data which wasn't good, take it all as a snapshot of our semi-historic February snowfall.
