Own It.

If you have to use someone else’s name or authority to get a point across, there is little merit to the point (you might not believe it yourself). If you believe something to be correct, focus on showing your work to prove it. Authority derives naturally from merit, not the other way around.’ - Kim Scott Malone

Never lend the weight of a superior to an order.

Don’t leave the meeting, boss’s office, or strategic planning day without the confidence you can give directions to the punters as if you came up with them yourself.

If the boss can’t show their working out, then you backward engineer the decision enough to explain it.

Then start looking for a new job.
