“dumbsize”

This word was coined in the 1990s. We all know what “downsize” means. When a company downsizes, it reduces the number of workers. When too many people have been let go and the remaining staff finds it difficult to carry out the work, it is called “dumbsizing”. In other words, the management was “dumb” to get rid of too many people!
