There is no constitutional right to be connected to a securities clearing house. If you fail one of your audits, you are out, and will lose a large chunk of money overnight. Failure to follow guidelines will get you failed. If they see anyone not wearing a mask, then you are deemed a systemic threat, and are out.
Lets say a firm is managing a trillion dollars in securities. You and I work at that firm. You say you will not wear a mask, and I say I will do what is ordered of me by my client, as long as it is not immoral or illegal. Masks are neither immoral nor illegal. If an auditor catches you not wearing a mask, then the company will be deemed a systemic risk, and will lose access to the securities clearing houses. That means they will lose the trillion dollars in securities, and the billions of dollars they make a year. The solution is simple, fire you, and give me a great big raise.
There are rules a really disagree with. The clear backpack I have mentioned, but the rule requiring executable code to go over dedicated lines is very painful to me. It means I have to physically go to a building, and cannot work at home. I really do not think it adds anything in safety. But breaking that rule could cost my clients billions, so I obey it. Then there is the rule against systemically essential workers going on mass transit. I miss being able to take the train, but really miss being able to take planes. Commercial planes are mass transit.
I connect following the rules of an employer/client/customer with being successful.
