Question for Dr John MacArthur

Is it unbiblical to belong to a Labor Union?
Answer:
No, not necessarily. The Bible does not say anything specifically about labor unions or political economics. That decision is at the discretion of each individual Christian. It is not more sanctified to be in a non-union shop than a union shop. Those things are political and economic. They are wisdom decisions that must be made with prayer and in keeping with biblical principles.
Question (continued):
Should a Christian strike?
Answer (continued):
When you join a union, you pledge a certain amount of support to that union. That is basically what it is, the union seeks to improve your job situation on the basis that you will be loyal to their pursuit. Once you have joined a union, you have a responsibility to keep your word to that organization, until such a time as you feel they have violated what is morally right.
In each situation, the Christian must decide for himself or herself whether or not striking is a right thing to do. If it is right, if it is equitable, then you can submit to the structure of that union and strike. If on the other hand, it is inequitable, unjust or unfair, then I think you can go ahead and break the lines and go across and work if you wish. But that is for every Christian to decide. The Bible makes no specific comment in regard to that particular issue.
But you need to get your Bible and turn to the sixth chapter of Ephesians. You need to read that passage carefully, since it lays out God’s ideal for labor relations. It talks about the proper behavior of both masters and servants, which corresponds to employers and employees. And after you’ve studied Ephesians 6, go to Colossians 3 and make a comparison of the two passages. Then ask God to give you direction in applying biblical truth and godly wisdom to your particular situation.
