Didn’t They Teach You When You Were A Kid . . .

. . . that embezzling money from a public school never works out like you want it to? Some just never learn:

A custodial secretary used her Queens high school as a personal piggy bank, stealing more than $60,000 in school funds, investigators charge.

Karen Nowaski, 37, allegedly forged and cashed phony payroll checks, increased her own hourly wage and claimed to have worked when she didn’t, according to a report by special schools investigator Richard Condon.

The secretary at Grover Cleveland High School also allegedly extorted $9,000 from another employee in exchange for not revealing his role in the scheme.
