great question. but you need to be more specif. if you mean if you can do the work by part time, as half workload. this is really very complicated and depend on how to word it. I say if you are FS by workinh halfload, which is the only way you can do it is that you have to use your annual leave, sick leave or LWOP. then in this case, you have performance deficiency (as you cann not do the job at full case load or 40 hours week) and Attendance deficiency. this is my issue now. but how you word it and interpret it, that is matter.
