I am wondering, for full time university teachers (not those who also have research responsibilities), what is generally the number of hours per week that they teach? I currently teach 20 hours per week and find the load quite heavy giving me little time to prep new modules with quality. Adding to that the responsibility of marking and it is not uncommon that I end up working more like 50-60 hours per week to teach 20.
Are these numbers average? High? Low?
