“For a true Christian, it’s ok to be a slave for others (with regard to work) but it’s not ok for us to use others as a slave (as Christ said, “treat others the way you want to be treated” – Luke 6:31)

That’s the difference.

Why?
We cannot do evil toward others, e.g. using or exploiting them but the Bible also teaches us to “not resist an evil person” (Matthew 5:39) who harms us (so, we’ll be blameless and let God judge them righteously on that Great Day).

It’s ok to serve your employers as a slave.

It requires great humility to do this.

Every evil/unjust treatment endured ‘rightly’ merits great rewards and honour in the afterlife for those who obey.

Our current temporal sufferings are nothing compared to the glory which shall be revealed in us.

“I consider that our present sufferings are not worth comparing with the glory that will be revealed in us.” (Romans 8:18)

Their secret intents to use you spitefully will be revealed one day too:

“This will take place on the day when God judges people’s secrets through Jesus Christ, as my gospel declares.” (Romans 2:16)

Endure it because they can’t change from their evil ways and do good to you instead:

“until the Ancient of Days came and pronounced judgment in favor of the holy people of the Most High, and the time came when they possessed the kingdom.” (Daniel 7:22)

“Bondservants, be obedient to those who are your masters according to the flesh, with fear and trembling, in sincerity of heart, as to Christ; not with eye service, as men-pleasers, but as bondservants of Christ, doing the will of God from the heart, with goodwill doing service, as to the Lord, and not to men, knowing that whatever good anyone does, he will receive the same from the Lord, whether he is a slave or free.” (Ephesians 6:5-8)
