safety, SpartanNash will not tolerate acts or threats
of violence, intimidation, harassment or coercion
in the workplace. You should report immediately to
your supervisor, Human Resources’ representative
security, or asset protection any behavior
that threatens the health and safety of people or
property, or has the potential to become violent.
Imminent threats of violence or physical harm
should always be reported first to local law
enforcement (call 911).
Also, you are strictly
prohibited from bringing or carrying onto
SpartanNash property or in SpartanNash vehicles
any weapons, firearms, ammunitions, explosives
or incendiary devices. The only exception is if you
are in a security position that requires as a part of
your job you carry a weapon or firearm. If you are
in a State that permits firearms to be stored in a
personal vechicle in a company parking lot, you
may do so, provided that you are properly licensed
or permitted to do so, the gun is safely stored
out of sight and the vechicle is locked. "
