Putting on a uniform and Sartre's bad faith are, so to speak, examples of each other. The agent adopts some subset of their own humanity as the totality, if only for a time, of their existence. There is no essential difference here between these modes of refusing total agency; indeed the willingness to adopt the constrained mode of one's office, whatever it is, can be seen as the highest luxury there is.
Everywhere we find ourselves swaddled like babies in legalism; the CEO's sole directive is to render profit to his shareholders. So he becomes gloriously bound to his duty, and unaffected by the yawning, ever-stretching plain of choice and moral repercussions that seems to follow actual freedom like a shadow.
