Types of conduct punishable by termination.

What manner of misdeed can get a teacher punished or fired these days?

The list of offenses is much longer — and the potential penalties stiffer — now that teachers unions cannot negotiate working conditions under Act 10.

Administrators say they want to cover all possible situations; some teachers say the rules are too vague or overreach. Here are some examples of forbidden conduct, drawn from employee handbooks in place last year:

Smoking tobacco on school grounds. (Port Washington, Fort Atkinson, Mequon and many other districts)

Boisterous or disruptive activity in the workplace. (Bowler)

Expressions outside of work that “disrupt harmony among co-workers or interfere with the maintenance of discipline by school officials.” (Nekoosa)

Failure to report a colleague’s suspected improper use of social media. (Bayfield)

Taking excessive breaks or gambling during work hours. (Independence)

New dress codes have received attention around the state as administrators have pushed for more professional attire.

Oak Creek barred “trendy clothes that adolescents and teenagers are wearing.”

Colfax banned jeans, or “skirts that ride up beyond mid-thigh when sitting.”

In Hartford, employees were blocked from wearing items advertising competing school districts.

The Clinton district held students and teachers to the same standard: no “hair color, hair styles, piercings, or make-up that draws undue attention.”

Many districts ban visible tattoos.

The result of these formal written behavior codes, teachers say, is a more buttoned-down — or buttoned-up, as the case may be — and less freewheeling work environment.
