STANDING ON YOUR CONVICTION

"THERE are certain Jews whom you have set over the affairs of the province of Babylon: Shadrach, Meshach, and Abed-Nego; THESE MEN, O KING, HAVE NOT PAID DUE REGARD TO YOU. THEY DO NOT SERVE YOUR gods OR WORSHIP THE GOLD IMAGE WHICH YOU HAVE SET UP.”
Daniel 3:12 (NKJV)

The fact that you are appointed to the position of power by someone does not mean you should disregard God's command or His injunction that you know in order to please the person.
The three friends of Daniel that were appointed as the heads of the province of Babylon knew they should not bow to any graven image, according to God's commandment to the Jews, thus, they should not fear and Nebuchadnezzar and disobey God (Exodus 20:3-5).
If you are privileged to serve under a leader who does not know God, If he or she gave a command that is contradictory to that of God, you should rather obey God's command than the command given by your boss: "BUT PETER AND JOHN ANSWERED AND SAID TO THEM, “WHETHER IT IS RIGHT IN THE SIGHT OF GOD TO LISTEN TO YOU MORE THAN TO GOD, YOU JUDGE" (Acts 4:19 NKJV).
The above Bible passage was the statement made by Peter and John to the religious leaders who told them to refrain from preaching the gospel of Jesus Christ Jesus. The apostles put the question before them that they should also think over It If It was right to obey them rather than God (Acts 4:19).
This shows to us that a believer can stand on his or her conviction and be firm about it—without being rude or cheeky or disrespectful.

If you were given such an instruction, what will you do? Will you consent or disagree with them and be on the Lord's side?
It is taught in the Bible that believers should be subject to the authority; under whichever authority he or she may find himself or herself. In Paul's words to Titus who was the Bishop of Crete, he told him to emphasize this:
1 REMIND THEM TO BE SUBJECT TO RULERS AND AUTHORITIES, TO OBEY, TO BE READY FOR EVERY GOOD WORK" (Titus 3:1 NKJV).
In this era of social media where freedom of speech is being emphasized, many talk to those in authority rudely, using abusive words. Under fundamental human rights you may be considered that you have the right to do that, but as a believer, It is not biblical—not in line with God's Word: "TO SPEAK EVIL OF NO ONE, TO BE PEACEABLE, GENTLE, SHOWING ALL HUMILITY TO ALL MEN" (Titus 3:2 NKJV).
When you are asked to compromise your faith or stand, you can say No without being rude and abusive.
That is what is being taught here; we are not asking you to go out there and be insulting or denigrating those who are in authority.
Peace.
