person who approached me thinks CA has a law that would "force" employer to supply shoes if this is indeed a MUST!
As near as I can determine this is what he could be talking about.
Your CA Labor Code, section 2802 (a) provides that "the employer shall indemnify his or her employee for all necessary expenditures or losses incurred by the employee in direct consequence of the discharge of his or her duties, or of his or her obedience to the directions of the employer...."
Briefly stated, if that's possible with "legalese" says: If an employer requires employees to wear a uniform, the employer must purchase and pay for maintenance and cleaning of the uniform.
It would seem that if the employer requires "dress shoes", under the aforementioned Labor Code, the employer would be required to buy the clothes and shoes, as well as provide money for maintaining the shoes and clothing.
The term "uniform" is broad. It means "wearing apparel of distinctive design or color."
The term "distinctive design" covers traditional "uniforms," such as one worn by law enforcement officers.
The definition of "uniform" also includes clothing of a particular "color" even if the clothes do not have an insignia or are not of a particular design.
An example might be, if the employer requires workers to wear a red shirt, even one without an insignia, the employer must pay for it because it is of "distinctive" color.
One might try to make the argument about "black, dress, polished shoes".
Employers seeking to avoid paying for clothing specify "dark" pants and "light" colored shirts instead of particular colors.
If you are required to wear black pants and shoes, but there is no requirement for the shirt, you are in a half-way no-man's-land.
The same issue if it's just "black polished shoes", rather than "Brand XYZ black shoes, highly polished".
However, if an employee pushes too hard, the employer often pushes back.
This is a very treacherous road he's about to tread.
