Front-line Clark County School District Police officers are getting raises averaging 16%, plus additional district contributions to their healthcare. The two unions — the Police Officers Association, which represents about 200 front-line officers and sergeants, and the Police Administrators Association, which represents the department’s handful of lieutenants and captains — are the last employee bargaining groups to settle contracts this year with CCSD. The School Board unanimously accepted the contracts on Thursday with no discussion.
