California state employees returning to offices under Governor Gavin Newsom's four-day work week mandate have reported significant health and safety concerns, including the detection of Legionella bacteria, bedbug infestations, and other pests. Service Employees International Union Local 1000 has raised alarms about "unsafe, or potentially unsafe working conditions" in several state government buildings.

One prominent incident occurred at the Department of Industrial Relations Building in Lodi, where the union reported that Legionella bacteria was detected last month. The bacteria, which can cause a severe form of pneumonia if inhaled through contaminated water mist, was found in a line connected to an icemaker. The Department of Industrial Relations acknowledged the findings and stated it is working with property management to implement corrective actions, including flushing plumbing fixtures and the water system.

The union also noted that other buildings with past health incidents are being monitored, including offices for the California Public Employees' Retirement System. Separately, employees at the California Department of Education discovered a bedbug infestation last month. A spokesperson for the Department of General Services stated that the situation is being addressed and that a building-wide treatment is under consideration.

In addition to these issues, union claims include reports of cockroaches in state facilities. SEIU Local 1000 has emphasized that if the state requires employees to return to the office, it must ensure a safe working environment. "State workers deserve fair pay, affordable healthcare, telework that works and workplaces free from hazards," the union said in a statement.

The return-to-office directive has become a point of contention as the union engages in contract negotiations with the state regarding pay and telework policies. Governor Newsom has maintained his stance on the mandate, stating in a press conference that he believes people returning to work is "a healthy thing for their mental health."
