Step-by-step explanation:
In the state of California, the CA State Board of Pharmacy does not require a specific minimum number of pharmacists to be a member of a pharmacists' labor union. The decision to join a labor union is a personal choice made by individual pharmacists based on their own interests and circumstances. Being a member of a labor union can provide pharmacists with various benefits, such as collective bargaining power, representation in workplace matters, and access to resources and support. However, it is important to note that being a member of a labor union is not mandatory in order to practice as a pharmacist or be licensed by the CA State Board of Pharmacy.
