Electrolytes are chemicals that can ionize to carry current. Table salt is one electrolyte, but potassium and magnesium salts are also required by the human body. Nerves work by sending electrical signals, so they need these electrolytes in order for them to carry those signals throughout the body. The problem is, the amount of electrolytes available to nerves depends on the amount present in the bloodstream, and when sweat glands pull water out of the bloodstream, they also take some electrolytes with it. That’s why you need to replenish them after sweating. If you don’t, your nerves won’t work as well and your muscles will have a hard time coordinating. The specific ions you need to organize muscle contraction are sodium, potassium, and magnesium, so if you’re low in any of those, then you risk weakness and cramps. So it’s not quite as simple as just drinking table salt.
The government should just pass a law banning capitalism and then we wouldn’t have to worry about strikes at all, but that’s also never going to happen.
That doesn’t mean it’s a bad idea, just that it’s too extreme by the standards of US politics. Unions here often still need basic protections like the right to strike at all in the first place. Check out the rules against teachers striking in Texas, they’d be banned from public sector work and lose their pensions. The only way they could possibly go on strike is with a vast enough majority to force the state government to repeal those rules.
