[All information taken from the Bureau of Labor Statistics except where noted.]
First up, the entire power grid would go down. 100% of power plant operators, distributors, and dispatchers are men. Now, it's possible that there are a few women working in these occupations, but however many there are, they do not make up even 1% of the total workforce, so statistically, 100% of the workforce is male.
91% of the nation's electrical engineers are men, and if they don't show up for work, there is no one to monitor and manage the nation's electrical supplies. Assuming some automation (designed by men, naturally) kicks in for the day, we had all better pray there are no problems. 97.6% of electrical power line installers and maintenance workers are men.
Lights out, ladies and gentlemen.
Don't bother turning on your taps, either. Or flushing your toilets. 95.5% of water and liquid waste treatment plant and system operators are men.
Think you might be able to get out of town for the one day the men don't show up?
Planes are out.
95.9% of aircraft pilots and flight engineers are men. If you happen to find a plane with a female pilot, don't get too excited. 98.4% of aircraft mechanics and service technicians are men. You can, however, be assured of your comfort as you sit on a pilotless aircraft that has no mechanic for pre-flight clearance, because 77.6% of flight attendants are female.
Should you be lucky enough to find a female pilot and a female technician to clear you for take-off, you still have some praying to do. Statistically, 0% of air traffic controllers and airfield operations specialists are women.
Of course, that doesn't mean there are ZERO ladies working in air traffic control. There just aren't enough to constitute even 1% of the workforce.
Trains, of course, are also out.
100% of locomotive engineers and operators are men, as are 100% of the workers who operate railroad brake, signals and switches. 94.4% of railway yardmasters are men, but if you chance upon a female yardmaster, it won't help you much. She can't operate the trains.
You might have better luck with bus drivers, almost half of whom are women.
But the streets are likely to be chaos. And there won't be anyone on hand to help you navigate that.
87.4% of police and sheriff's patrol officers are men. 96.6% of firefighters are men. 68.8% of Emergency Medical Technicians and Paramedics are men, so if it all goes tits up and you get hurt, there's a small chance you might make it to a hospital.
I hope you don't get too badly hurt, though. 65.7% of all surgeons are men.
Maybe you should just work from home? In the dark, mind you. With no running water.
Uh-oh. Looks like that might be a problem, too.
For all computer and mathematical occupations combined, 74.4% of the workforce is male. Computer network architects, who design and implement all our computer based communications systems are 91.9% men. And 94.2% of radio and telecommunications equipment installers and repair technicians are men.
Looks like that plan is fucked.
Hope it doesn't get too hot, or too cold the day men don't show up for work. Even if you had power, which you don't, you would be hard-pressed to get anyone in to take a look at your wonky air-conditioner or furnace.
98.4% of heating, air-conditioning and refrigeration mechanics and installers are men.
Oh well. Guess you'll have to mosey on down to the local café, which has no power either, but what's logic and consequence anyways? Be careful when you step over all that accumulating garbage! Remember that most EMTs are men, and they've taken the day off. Don't want to get hurt now.
Most garbage collectors are men, too. 93.4%, to be exact.
You'll need to stop at the bank first, for a little cash injection.
Oops. Don't bother.
The machine hasn't been filled with money today. 81.5% of security guards and gaming surveillance officers are men. It's unlikely the banks would be functioning anyways, with no men at work. 72.1% of all securities, commodities and financial services sales agents are men. 72.6% of the nation's CEOs would be taking the day off, along with 70.9% of all the general and operations managers.
Don't count on getting a weather report today. Statistically, 0% of the nation's atmospheric and space scientists are women.
Actually, don't plan on acquiring pretty much anything today. The workers in the entire production, transportation and material moving occupations are 78.2% men. Not only will no goods be moving on the day men go on strike, they won't be made, period. 82.4% of all the industrial production managers are men.
Nothing will be built or extracted from the earth in terms of raw materials. 97.5% of that workforce is male.
Nothing will be installed, maintained or repaired. 96.8% of that workforce is male.
If men took a collective day off, we would instantly be without power, without the means to communicate, without protection, without water, without trucks bringing us the food and products we take for granted, because men are the ones who provide all those things.
