When older/senior employees, who have worked in one company/location for most of their working lives, adopt shakespeare's second childishness in the truest sense, and reduce to toddlers in the playground. It normally is characterised when they are merged, or taken over.
Cause: Employees who have been in one comapny too long, way too long, and do not have a clue of the working world outside of their office cubicle of 15+ years.
Symptoms: General rebellion with no apprant reason. Broken urinals, cisterns, degrading scribbling/graffiti on company pemises/walls sometimes seen.
Cure: Fire them/spank them.
First seen in Marconi in Beeston in 2006, when they were taken over by Ericsson.
I hope the employees don't go Marconi on us.
