Peter, read again, the point I made is skivers are in both private and public sectors, however they are easier to handle and get rid of in the private, whether that is because of strong unions or lax management. Also if your wife brings work home she needs time management, it's not necessary.
Anyone who regularly brings work home needs an assistant, not better time management.
I don't suppose that applies to teachers who already work 7 30 to 5 30 then bring marking, report writing, special need assessment reports etc home. Of course not as teachers are lazy overpaid skivers who are easy to criticise but few people are willing to give up their own, far more difficult, careers to improve the lot of the next generation.
