You know, I can entirely understand the idea of not wanting to do specific tasks at work, or even not wanting to do any work at all. Personally I think I would feel frustrated with being paid to do nothing, but I can see how it would seem an attractive proposition. And constructive 'delegating' to preserve the appearance of work without having to do anything oneself, well, that's practically a requirement for some jobs. But I struggle to get my head around the mentality which leads somebody to be pathologically avoidant when it comes to doing any of the work pertaining to their post, yet proactively obstructive in impeding, undermining and otherwise sabotaging everybody else's attempts to fill in the gaps.
But then, if odd behaviour was a renewable energy source then this institution would be a veritable powerhouse.
