Go around work telling everyone that the injections cause blood clots. How it is 100% the injections fault. Eventually the boss will think, "Hey, I got the injections. Maybe what's happening with my leg is caused by a by a blood clot". You can't convince people of the truth by telling them the truth. Instead you have to make them think that they were the ones who figured it out. Also, you can't tell people the truth after the fact. - In other words, if your boss finds out that he has a blood clot, and then you say it's from the shots, no one will believe you. But if you tell your coworkers that the shots cause blood clots, and then later on in the future someone gets a clot, they will put the two pieces together themselves. Meanwhile, if you want your boss to die, or suffer the full consequences of the injections - Tell the workplace that *the wacky conspiracy theorists* all think that the shots cause blood clots. That only *wacky conspiracy theorists* would ever believe anything so stupid. The boss will be too afraid to get checked for blood clots, or do anything about his leg, because the main reason he got the injections was so that he wouldn't ever be associated with the people who are called bad names. Like racist or conspiracy theorist. And once the boss suffers the consequences of the injections, and suffers the consequences of avoiding being called bad names, hopefully it'll convince some coworkers that it's better to be called bad names than it is to die.
