How will they pay their teaching staff more?
According to the OP’s link Gove doesn’t mention that teaching staff will get more pay, he said, “Teachers should definitely be paid more than they are at the moment”.
There’s no commitment there at all.
I would hardly expect him to say “Teachers should definitely be paid less than they are at the moment”.
Specially as he is already probably the Sectary of State for Education who inspires the least confidence ever from teaching professions. I see no reason why he would want to antagonize them even further.
Non-committal words cost absolutely nothing at all, so I think it was a rather nice touch that Gove used such warm and generous words. Even if they won’t pay the shopping or have any value at all.
