Time magazine last month had a cover story bashing teachers that was not just one-sided, but as misleading as less-respected voices on radio and TV.

This month, such ill-founded resentment may echo in grumbling about schools’ holiday breaks or misinformed complaints that teachers don’t work enough, are overpaid, have exorbitant pensions, and cause local property owners to shoulder inflated real estate taxes to fund lousy-performing schools.

Teachers must be defended.

It’s elected representatives more interested in re-election than governing for the good of constituents who’ve neglected their duties. Faced with budget challenges, lawmakers must cut government where permissible (knowing some citizens will object), or raise revenues like taxes (knowing some voters will object). So most don’t, whether Peoria, Springfield or Washington.

As to the tired complaints: School boards decide the length of school years, but most teachers work a 174-day year. Since class days are fewer than eight hours, it’s not illogical to assume teachers work “half a year.” However, as Pennsylvania pal and colleague Walt Brasch shows, “There are 365 days in a year. Subtract two days a week, which the average worker does not work, and that leaves 261 days. Next, remove 10 days of vacation. That leaves 251 days. Next, there are state and federal holidays, bracketed by New Year’s Day and Christmas. Generally, most businesses accept the 10 federal holidays. That leaves 241 days.”

So 174 is less than 241, but teachers’ days and weeks are longer than eight hours and five days. Teachers start working before classes, stay late to prep for the next day or student activities, and then, at home most nights and weekends, grade papers, prepare lesson plans, study teaching methods, and keep up with their specialties.

Teachers spend holidays – any break, from Casimir Pulaski Day to summer vacation – catching up on scoring tests and grading, planning for the coming semester, attending professional conferences, and taking classes to stay certified and improve their teaching and expertise. It’s demanding.

“Teaching has a high burnout rate,” said Victor Devinatz, Distinguished Professor of Management at Illinois State University. “Many leave the profession within five years.”

As for teachers’ pay, the starting salary for Illinois teachers – who must have a college degree – is $37,500, according to the TeacherPortal.com survey cited in Forbes magazine, and the average wage overall (including Chicago and affluent suburbs) is $58,686. That seems generous, but it’s below those with similar education and experience. The Economic Policy Institute says public school teachers are paid about 19 percent less than professionals with similar qualifications, and some, notably in sciences and math, may be paid less than half of what others with their backgrounds receive.

Critics also complain about pensions. In Illinois, the problem isn’t teachers, who paid their share of contributions, but the failure of Democratic and Republican administrations alike to meet government’s legal obligation to contribute to the pension system.

(Also, public employees like teachers don’t receive Social Security for their years of working for government.)

Like every workplace, education has lazy or less-competent teachers, but contrary to Time and education-bashers teachers – even tenured employees – can be fired for cause. Also, some parents are slackers, doing little to help kids learn, instead instilling in their families unfair stereotypes of teachers.

Finally, taxpayers have a point about funding schools. The notion of school districts depending on property values and taxes is outdated and must be changed to let less affluent areas have the same caliber of education as richer districts. Schools get less help from state and federal sources than local taxes. Urban and rural areas don’t have the property tax base that suburban areas do, yet fixed expenditures such as buses and books make the burden heavy there.

Many politicians claim to support education, but action falls short of oratory.

Teachers must be defended.
