Argue and you lose....
Some years ago while working for a south asian airline, reported at dispatch to find the co-pilot madly puffing away on no less than two, and announcing his intentions to one and all that the recent directive to flight crew to not smoke on the flight deck, period, was nonsense. Smoking was still allowed in the cabin.
The dispatcher called the DFO and said co-pilot announced his opinions directly, IE: ..."it is my right to smoke".
The co-pilot was no more...replaced for the flight and employment terminated, forthwith.
