Correct, it's brain blowing managers don't have to pass the referees exam. Fat too often I've seen them gob off about a correct decision through ignorance. Then a few weeks later they gob off about rubbish referees totally oblivious to the fact 50% of qualified referees give up within two years (last I checked and including me) due to abuse/threats/assaults.
I refereed around Stafford, statistically a safe place to referee. Stafford Referees. Association (40 members), had three members hospitalised in two seasons. Two on the pitch, one in a pub by someone he sent of two weeks earlier.)
In my last match I was hit in the leg by a corner flag thrown at the referee (I was a linesman as was.) The player should have walked for a horrendous tackle with seconds left but aware of the financial ramifications on a pay to pay player he went yellow. A few weeks later I moved to a statistically dangerous place to referee and retired.
Personally I was compotent, no more. I may have made hamlets level but no more. Sadly I knew a lad tipped for the top.who retired after an assault. His boss wasn't impressed he had time off.
