Well, think about it from that perspective where you are an business owner. Your business is part of your extended family and if someone does not feel great about being part of your extended family, they rightfully will be booted out and the sooner that happens the better for company.
As an introverted person I can only suggest for you to make your own business or go freelance, because you are not going to change rules for other people how they should behave only because your comfortable family scale is much smaller.
Any business is a family - the problem here is that it is not yours(or you don't perceive it as yours).
From the perspective of a business owner, an employee is someone paid to do an actual job. They either do the job they are being paid to do, or they're fired. They're not part of the business owners perceived extended family unless the business owner is mentally ill. Employing someone to be a pseudo-family member is psychotic and probably illegal.
It all depends on what you think as an actual job. An actual job of any worker is NOT RUINING BUSINESS - it is not only illegal but also criminal. So, your actual job is following rules of a company and if they make you wear uniform, because that would make you not stand out, you will have to oblige - according to the rules of a company where you are member of that extended family. Your teenage angst is not only wrong, but will mean booting you out of a company.
Like I mentioned before, if you have problems with business that is employing you and THEIR set of rules, that YOU have to follow and that is part of YOUR ACTUAL JOB, then you better SEEK OTHER JOB or CREATE YOUR OWN. No one is forcing you to follow rules - any rules, even CONSTITUTION(where whole NATION is regarded as an EXTENDED FAMILY), but you have to be ready to face consequences of alternative and that is INSANITY - not illegal, because you have not agreed on those rules, but good luck on imposing YOUR RULES or lack of rules on others... and have probably a very short journey in this fight YOU vs WORLD.
The world sucks if you have to adapt, but it is not right to enforce something onto others for your own comfort unless you pay others compensation. That is the base of any business.
