CONCORD, N.H. — Gov. Maggie Hassan vetoed a bill Monday aimed at protecting New Hampshire state employees from abusive work environments, saying it was well-intentioned but unworkable.

Lawmakers passed the measure after hearing from current and former state workers who said they experienced workplace bullying. It would have required state departments and agencies to develop policies to address harassment.

But Hassan said the legislation’s definition of “abusive conduct” was overly broad and would have made the most routine interactions potential causes of action. For example, workers could claim abuse if they believed they had “unreasonable” workloads, felt co-workers weren’t answering emails in a timely manner or had received constructive criticism from supervisors or peers, she said.

“The bill also attempts to legislate politeness, manners and the interpersonal relationships of co-workers,” Hassan said.

The Democratic governor said state employees deserve respect and the opportunity to work in respectful environments, but she argued the legislation would lead to a dramatic increase in lawsuits, which would in turn hinder productivity.

The bill’s sponsor, Rep. Diane Schuett, said she hopes lawmakers will override the veto.

“We all know there’s bullying in school, and just because someone graduates from school, doesn’t mean they stop doing it, and it carries over into the workplace,” she said. “It undermines the efficiency within state government if you end up with one or two employees being harassed on the job, either by another employee or a supervisor, and you end up with the entire agency being aware of it and feeling like they have to pick sides.”

Schuett, D-Pembroke, and other supporters said the state has no written policy against abuse in the workplace nor any office procedure to follow to address such issues. But Hassan said existing state rules give employees an avenue for making complaints.

Diana Lacey, president of the State Employees’ Association, disagreed. She said in the two years since the bill was first introduced, the governor has done little more than have the state personnel division develop an online “Respect in the Workplace” training presentation.

“It just feels like more stalling,” she said. “The governor has the power to issue an executive order to take this more seriously … If the governor wasn’t going to support the legislation, the governor’s office should’ve pitched an executive order and has not done so. So we’re very upset.”

As for the concern about litigation, Lacey said state employees already have been using the courts to seek relief. She said the bill would help create a well-structured path to resolve complaints without litigation.

Business groups, including the Business and Industry Association of New Hampshire, praised the governor’s decision, agreeing with her that creating such requirements for public agencies would be a step toward extending them to the private sector.
