Last week, the press started to notice that security screeners at airports (who have been ordered to work without pay) are starting to call out in growing numbers. It's not too hard to see where this could end up. Indeed, signs are already there. "The Transportation Security Authority said it had closed a security checkpoint at BWI Marshall Airport Saturday evening because of a shortages of screeners. In a Twitter message sent Saturday evening the agency said it “will be exercising a contingency plan” at BWI “due to excessive callouts.” https://www.washingtonpost.com/loca...5fed1b7a081_story.html?utm_term=.1015c338ae3b Right now, this is a somewhat local story involving one airport. It just happens to be one airport that handles about 35% of the domestic air travel in and out of the DC Metro area. Every day, approximately 2 million Americans fly, the vast majority on business. It would be perfectly resasonable at this point for any or all of these unpaid people (doing a very thankless job), to walk off. Public opinion would be firmly on their side. And they wouldn't have to go out at one time either. Anyone watching The Weather Channel these last few days can see that. Strike O'Hare and Midway for just one day, and the resulting cascade of cancellations and flight delays will spread to every airport in the country. It will take days to clear the backlog (having had some experience at being stranded myself...). At least a million people will face total cancellations or long delays in rebooking. Hotels, rental car companies and airport restaurants and bars will do well. But as the sales reps, consultant, technicians and managers who fly every day find thier work impeded or delayed, the pain will spread quickly, throughout the entire US economy. If not O'Hare, then Denver, Atlanta, Dallas/Ft Worth, Charlotte, Kennedy/LaGuradia or Logan, and they can cripple air transport. A rolling series of walkouts like this over several days would bring air travel to a virtual stop. And the captains of industry will be the ones howling. And none of them give a good damn about Trump's ridiculous wall. And the public won't blame the workers for staying home when they're not getting paid, either, no matter how hard Fox and the right wing noise machine tries to demonize them.
