Figures were released (via Dáil written answers) for Irish third-level institutions of the percentage of staff that are academic and non-academic.
This is a screenshot from the post.
UCD and TCD are the only institutions where academic staff are less than 50%.
The average percentage of academic staff across Irish universities is 52.4%. Across all universities in Australia, the interesting article here from Australia states that the average percentage of academic staff is 45%. In the UK it is 48%. There must be a balance point that maximizes efficiency of the system. I find it hard to believe that less than 50% academic staff is optimal, but I haven’t done any studies.
The Economist posted a humorous 1955 article by Parkinson, which contains Parkinson’s Law “work expands to fill the time available for its completion” and a funny yet realistic treatise on the growth of public administrative departments.
