Hello Avia Makky,
Do you have a Tableau workbook demonstrating what has been attempted so far? I understand the desire to indicate that all time points for an employee between start and the next date as relating to a status of some sort but I'm not clear what the final outcome or goal of this request relates to. What is the overall goal of the visualization that is being built? Providing the high level goal will often result in a number of different comments and perspectives on how to achieve a visualization that best expresses the goal.
