The Agnostic Manifesto: If I don't know something, I don't say I know it.
I do not think that jumping to rigid positions quickly is a good strategy. I am probably talking more psychology than philosophy at this point. I have read that openness to new experience is actually a core trait, and it is hard to imagine this not being involved.
Essentially, if you're allowing your employer to walk all over you, that's on you.
Woo-hoo: no limits whatsoever on employer behavior. That should work out well.
Let me propose another idea: Both employer and employee are stuck together in a system. Neither should have their actions go unchecked. Both should bring reasonable behavior to the table. Occasionally the law can assist with this.
