I don't have to like you, in order to work with you.
@garyackerman that's, true. That adds quality to the quantity.
But having someone you disagree personally with, genuinely helping you deliver a product to a customer- is better than none at all.
That's an example of keeping it professional at work.
@lucifargundam And different perspectives contribute to (much) better outcome as well, but no one needs to be a jerk about it.
