(b) For the week in which the individual has been suspended or discharged for misconduct connected with the work, and for the five weeks which immediately follow that week, as determined in each case.
"Misconduct" means conduct which is improper, intentional, connected with the individual's work, within the individual's control, not a good faith error of judgment or discretion, and is either a deliberate refusal, without good cause, to comply with the employer's lawful and reasonable rules made known to the employee or a deliberate disregard of standards of behavior the employer has a reasonable right to expect, including reasonable safety standards and reasonable standards for a workplace free of drug and substance abuse.
In the event the discharge should be rescinded by the employer voluntarily or as a result of mediation or arbitration, this subsection (b) shall not apply, provided, however, an individual who is restored to employment with back pay shall return any benefits received under this chapter for any week of unemployment for which the individual is subsequently compensated by the employer.
If the discharge was for gross misconduct connected with the work because of the commission of an act punishable as a crime of the first, second, third or fourth degree under the "New Jersey Code of Criminal Justice," N.J.S.2C:1-1 et seq., the individual shall be disqualified in accordance with the disqualification prescribed in subsection (a) of this section and no benefit rights shall accrue to any individual based upon wages from that employer for services rendered prior to the day upon which the individual was discharged.
The director shall insure that any appeal of a determination holding the individual disqualified for gross misconduct in connection with the work shall be expeditiously processed by the appeal tribunal.
To sustain disqualification from benefits because of misconduct under this subsection (b), the burden of proof is upon the employer, who shall, prior to a determination by the department of misconduct, provide written documentation demonstrating that the employee's actions constitute misconduct or gross misconduct.
Nothing within this subsection (b) shall be construed to interfere with the exercise of rights protected under the "National Labor Relations Act," ( 29 U.S.C. s.151 et seq.) or the "New Jersey Employer-Employee Relations Act," P.L. 1941, c.100 (C.34:13A-1 et seq.).
