Writing a letter of complaint/concern to a unit director.A staff who voluntarily self demoted from a higher position to a lower position reapplied to be reinstated after six of being in the lower position. The staff was first approved, but later denied due his preferences. Not withstanding, another staff for another shift was grant the position due to personal reasons he had at home. The self demoted staff has seniority over the staff that was granted the position.When did we start impeding other staff promotion and granting other staff his preferences for personal reason?Comments from CustomerDiscipline: Not applicable
