Hello and thank you for entrusting me to answer your question. I am very sorry to hear that you were let go and have encountered these difficulties getting paid.
To answer your question, it is first important to understand the difference between discretionary
bonuses. Discretionary bonuses are paid at the discretion of the employer and therefore the employer has no obligation to pay them at all, even if it alludes to the fact that it will. Furthermore, since discretionary bonuses are not mandatory, they do not qualify as a "wage earned" until they are actually paid.
Performance-based bonuses, however, are bonuses tied to specific performance based goals and automatically must be paid upon an employee or the company meeting those goals. For example, if the company has an agreement with the employee in place that for any quarter in which the employee sells more than 1,000 widgets he gets a $1,500 bonus, that bonus would accrue and be considered a wage payable immediately upon that employee's sale of 1,000 widgets.
I bring this distinction to your attention because if a bonus was discretionary, an employer has no obligation to pay it and no obligation to make it a specific amount, even if a larger amount was previously promised. Thus, if your bonus was purely discretionary, no legal cause of action would likely arise from the fact that it was untimely paid (since it is not a "wage earned" until paid) nor the fact that a larger amount was previously promised.
However, if the bonus was performance-based, it would constitute a "wage earned" immediately upon satisfaction of the terms that trigger it. Thus, if your bonus was performance-based, your employer would have been required to pay it to you within 72 hours of your notification of intent to quit, assuming it had already accrued (Labor Code 201). Furthermore, failure to pay this bonus within 72 hours would give rise to a late penalty against your employer in the amount of your "daily rate of pay" for each day that the bonus went unpaid for up to 30 days. (Labor Code 203) However, keep in mind that this duty and this penalty only apply if the bonus is a "wage earned," and that is only the case if the bonus is performance based.
So to summarize, if the bonus is purely discretionary, there would typically be no duty to timely pay it or to make it a certain amount, despite previous promises of a higher amount. However, if the bonus is performance based, a duty would arise to pay it within 72 hours of an employee's notice that they quit and a penalty would be assessed for each day of non-payment up to 30 days.
