Mr Milloy, principal teacher of maths, is the only one of 29 promoted staff to enjoy a pay hike after the contentious PricewaterhouseCoopers job-sizing exercise.
It has left senior staff baffled, embarrassed and disappointed, as a TES Scotland spot survey reveals this week.
Mr Milloy's salary has gone from pound;37,782 to pound;39,099, a rise of 3.5 per cent. But the head of English, who runs the largest department , has had no August bonus.
Headteacher Mike Doig, who happens to be president of the Headteachers'
Association of Scotland, says: "The whole thing has gone down like a lead balloon."
The East Dunbartonshire secondary is one illustration of the amazement around the country at the outcome of the shake-up.
Two principal teachers of guidance and chemistry have been sized at different levels, although apparently doing identical jobs.
