'Teachers don't need to be able to spell' says Union?

In response to the Donaldson Review in Scotland which accuses teacher training institutions of letting incompetent and illiterate staff into the teaching profession, Tony Axon, of the lecturers' union UCU told BBC News,

"People may complain about spelling and grammar but these days we sit at a computer which works out much of that for you. Are those skills really as important as they used to be?"

Not entirely sure what can be said about that mind boggling comment really.
