The petitioners who are head load and General Workers, are not participated in the work carried on in the Port at Vizhinjam. The grievance projected in the above writ petition is the denial of employment to such workers, though the right to the members of the Union, have crystallized by Exts.P2 and P7. Petitioners have been consistently before this Court seeking conciliation insofar as participation in the work at Vizhinjam Port. According to them, the 6th respondent by sheer muscle power prevented the members of the petitioner/Union from working.
