Six unions representing county workers ranging from nurses and correctional officers to engineers and architects are pushing back against a health order that requires employees in high-risk job settings to get a booster shot.

In a joint letter sent on Tuesday to the Board of Supervisors and County Executive Jeff Smith, union leadership claimed that the booster mandate will cripple a workforce already under immense strain from the omicron variant and requested that county leaders find a way for those with approved vaccine exemptions to stay in their positions.
