Health Unit Coordinator Question:

Last year the department was given a task of disinfecting all rooms using a new sanitizing technique and I allocated duties to all staff members accordingly. One of them did not perform the additional duty too well so I distributed his duties among the rest of the staff who had performed well. Later I realized my mistake; not only other employees complained about being over-burdened but also the employee who had refused developed a habit of walking out on duties. Next time I was required to allot extra duties, I assigned him his part of the extra work and explained to him that his job will not be done by any of the other workers at any cost. I asked him to work extra hours in case he was unable to complete assigned tasks on time.
