If there is half an hour left of the regular work hours of a field worker, should he go back to the office?
Question

                What is the ruling on a field worker who moves from site to site for his work, when sometimes there is only half an hour left of his regular hours, and if he goes back to the office it will take him half an hour to get there, then his day will be over. Is it permissible for him to go home in this case? Or what should he do?.
Praise be to Allah.
    There is no doubt that you are required to be present for the 
    hours agreed upon in your work contract, and there are no exceptions apart 
    from occasions when permission is given for work purposes or for some need. 

    Based on this, you should inform your superiors of the 
    situation, and if they give you permission to go home, then you may go home, 
    otherwise you have to go back to the office. 

    And Allaah knows best.
