This is a common misunderstanding, let's recap the first amendment:
> Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech,
A civil contract between a company and individual does not fall under this at all. They could add anything to that contract and it is up to you whether you sign it. If a company demands you to walk to the office like someone out of Monthy Python's Ministry Of Silly Walks, they sure can. It's up to you whether you accept it. There are some explicit limitations to this (class discrimination, whistleblower protections etc) but beyond that, it's a free country.
