First, it is important to know if your commission meets the definition of "commission" under Labor Code § 204, which defines commissions this way: "The term 'commission wages' has been defined in the case of Keyes Motors, Inc. v. DLSE (1988) 197 Cal.App.3d 557, which held that commissions arise from the sale of a product, not the making of a product or the rendering of a service. The court further held that in order to be a commission, the compensation must be a percentage of the price of the product or service whic h is sold. (See also, O.L. 1983.11.25; see also Section 2 .5.4 of the Division of Labor Standards Enforcement Enforcement Manual.) The California Supreme Court in Ramirez v. Yosem ite Water C o., Inc. (1999) 20 Cal.4th 785, reiterated that the definition of commissions in Section 204.1 ap plies to all employees receiving commissions."
General contract terms apply to commission wage plans. An employer is required to act reasonably to allow the employee to obtain the benefits of the contract for a commission wage. The employer cannot time a termination or mislead the employee to cheat the employee into losing commissions, particularly IF the employee was the main person whose work resulted in the sale. The court in Wise v. Reeve Electronics, Inc. (1960) 183 Cal.App.2d 4 held that where the employee was the procuring cause of a sale, he is entitled to the commission “irrespective of the fact that the principal himself, or through others, may have intervened.”
If the employer terminates the employee's employment, thereby preventing the employee from meeting all the terms required to earn the commission, then the employee may be entitled to recover all or a pro-rata portion of the commission.
There is a lot of case law on this subject and it would take quite a long time to type out the law that pertains to every possible situation. You safest course is to take your contract to one or more experienced employment law attorneys with whom you can discuss the details of your situation and get an analysis based on the contract language and the facts.
