Can supervisors work during the free period. In our center we have a situation where the supervisors are delivering routes claiming that they have the right because it is the free period and anything goes and there is no additional help available. Supervisors working in our center has been a continuous problem and greivences have been filed on a fairly steady basis with not much alleviation of the problem. My question is that do I have any basis to file a greivence during this time period..
