National Lab workers call for director to step down amid ‘bullyism’ Workers at the National Public Health Laboratory in Kingston staged a lengthy protest on Tuesday, accusing the Director of National Laboratory Services, Dr Marlene Tapper, of creating a hostile work environment. Gathered in the lab’s parking area with placards, employees demonstrated from morning into the afternoon, claiming they felt victimised and uncomfortable on the job. The protest disrupted key services, including blood testing, as staff halted operations in what they described as necessary industrial action.
