Cal. Bus. & Prof. Code § 4113.6

(a) A chain community pharmacy subject to Section 4113.5 shall be staffed at all times with at least one clerk or pharmacy technician fully dedicated to performing pharmacy-related services. The board shall not take action against a pharmacy for a violation of this subdivision if any of the following conditions apply:
1. (1) The pharmacist on duty waives the requirement in writing during specified hours based on workload need.
2. (2) The pharmacy is open beyond normal business hours, which is before 8:00 a.m. and after 7:00 p.m. During the hours before 8:00 a.m. and after 7:00 p.m., the requirement shall not apply.
3. (3) The pharmacy’s prescription volume per day on average is less than 75 prescriptions per day based on the average daily prescription volume for the past calendar year. However, if the pharmacist is also expected to provide additional pharmacy services such as immunizations, tests classified as waived under the federal Clinical Laboratory Improvement Amendments of 1988 (42 U.S.C. Sec. 263a), or any other ancillary services provided by law, this paragraph does not apply.
(b) Where staffing of pharmacist hours within a chain community pharmacy does not overlap sufficiently, scheduled closures for lunch time for all pharmacy staff shall be established and publicly posted and included on the outgoing telephone message.
(c) A chain community pharmacy shall post, in a prominent place for pharmacy personnel, a notice that provides information on how to file a complaint with the board.
