(b) Section 3(m)(2)(A) also provides that an employer that takes a tip credit against its minimum wage obligations to its tipped employees must inform those employees of the provisions of that subsection, and that the employees must retain all of their tips, although the employer may require those employees to participate in a tip pool with other tipped employees that customarily and regularly receive tips.
(c) Section 3(m)(2)(B) provides that an employer may not keep tips received by its employees for any purposes, including allowing managers and supervisors to keep any portion of employees' tips, regardless of whether the employer takes a tip credit under section 3(m)(2)(A).
