Legal analysis: this fixed time does not belong to the socially necessary labor time of teachers. It is just the hour product of the specified 8-hour working days multiplied by the natural working days. Compared with this legal amount of time, in the actual calculation of teachers' workload, we often use the actual time of teachers' work, which is multiplied by the corresponding weighted number after scientific calculation and processing.
