Irregular attendance is different from negligence because the latter connotes the sense that the workman is present on duty but is neglecting his work while irregular attendance shows that on certain occasions the employees was not on duty at all. It would, therefore, not be proper to charge an employee with negligence when he is in fact guilty of only irregular attendance. systematically leaving work without permission is loitering. when, therefore, a person systematically absents himself form work without permission such an act amounts to gross of discipline entailing the extreme penalty of removal from service. In other words, when a workman makes it a habit of loitering outside his place of work without permission to leave the work and refuses to give up such a habit when advised to to so repeatedly, it would be an act of grave misconduct. Such misconduct when proved would justify the punishment of dismissal.
