General assistants (GA) at high schools are being taken for granted, claims a St George worker.
Neil Clarke, 50, of Carlton has worked as a full-time GA at Georges River College's Hurstville Boys campus for more than 12 years.
He said he was being transferred to St George Girls High School and his current position was being advertised to two-and-a-half days a week.
Some of the Hurstville students are angry about the move and want Mr Clarke, or "Krusher'' as they know him, to stay.
Mr Clarke said his duties included setting up the hall for assemblies, mowing the lawns, fixing broken windows and lights, and general classroom maintenance.
"I'm lucky because I can go to another full-time job, but the point is that my job here cannot be done in two-and-a-half days.''
"They say it's [my transfer] because of falling student numbers, but our student numbers have been below 500 for four years now and they've only just realised,'' Mr Clarke said.
"The Department of Education's staffing department has been telling me that this has been happening at 20 other school and there are many GA jobs advertised on the department's website as casual positions.
''Students and taxpayers deserve better.''
Billy Billiris, a former student at the school, said "Krusher'' would be missed.
"When I first came to the school he was very supportive and kept me motivated to stay in school more than the teachers,'' Billy said.
"Every kid in the school knows him, gets along with him, and everyone is angry that he is leaving.''
A department spokesman said Mr Clarke was being transferred because school enrolments had fallen below the threshold for a full-time GA.
"When enrolments at schools fall, very minor maintenance issues are reduced,'' the spokesman said.
Mr Clarke's last day at the campus is Friday May 16.
