Ruling on going on strike
Question

                What is the ruling on going on strike to
    attain some workers’ demands or to improve their situation?
Praise be to Allah.Striking is a breach of the contract between the worker
    and his employer, and Allaah calls on us in His Book to honour and uphold the contracts
    that one person may take upon himself towards another person. So the worker has to do all
    the work that he agreed to do in a manner that pleases Allaah and in accordance with the
    aayah (interpretation of the meaning);
“O you who believe! Fulfil (your) obligations…”
    [al-Maa’idah 5:1]
Strikes are often accompanied by trouble, discord and violence, which
    is unacceptable in Islam because of the Fiqhi principle that warding off evil takes
    priority over achieving benefits. There are a number of other means which can be resorted
    to in order to achieve one’s goals, and which may be more effective than striking. A
    wise man would not leave any legitimate avenue unexplored.
As for stopping work because one has not been paid, this is
    permissible, because in this case the employer is in breach of contract, so the worker has
    the right to stop work until he gets paid. The Prophet 
 (peace and blessings of Allaah be
    upon him) said: “Give the hired worker his wages before his sweat dries.” (Narrated
    by Ibn Maajah). And Allaah knows best.
