Just because you can flip the finger to a police officer, doesn't mean it's a good idea.
Just because you have the right under the law to __fill in your own action here___ doesn't mean it makes sense or won't cause havoc.
Just because you are allowed to work from home, doesn't mean that YOU, with your own work productivity issues -- be they technical or innate -- should.
Just because you can choose not to tell the truth, doesn't mean your choice won't have repercussions now or in the future.
Just because one person does something, doesn't mean you should too (or even that it's allowed).
Just because ... oh I could go on.
While rights and rules leave significant leeway in behavior in society and in the workplace, it remains squarely on the person to choose how to act, how to work, how to react based on that person's skills, situation, capacity, etc.
It feels like common sense, but what is common to me, may not be common to you. What is clear is that reading the environment -- understanding your place in it -- is a vital step in action and reaction. When you're the boss, more leeway in some things, much less in others. When you're an employee, understanding what the rules are -- written and implied -- is critical to success. When you're the agency, understanding and adhering to the extra layer of client norms is key to keeping that client, regardless of how good the work product is. When you're a citizen, grasping authority, rights and boundaries can be the difference between "thank you m'am" and "spread 'em."
Sort of like when your mother said "and if Jeff jumped off a bridge, would you do that too?"
Be alert. Know yourself. Understand that your choices have consequences, good and bad.
