It is unlawful to retaliate against an employee for taking protected medical leave. It is not unlawful to reduce your hours for just about any other reason, even if it follows the taking of that leave.
It would be helpful to know far more information before someone could answer your question. The size of your employer, how long you have worked there, how many hours you worked in the year before the leave, the notices provided to you by the employer when you took the leave, the nature of your job, and several other facts would need to be known.
If you believe your hours have been cut in retaliation for taking the medical leave, then it would be prudent to locate and consult with an experienced employment law attorney as soon as possible to explore your facts and determine your options. I would suggest you look either on this site in the Find a Lawyer section, or go to www.cela.org, the home page for the California Employment Lawyers Association, an organization whose members are dedicated to the representation of employees against their employers.
Most employment attorneys who practice this area of law offer a free or low-charge consultation and then if the matter has merit and sufficient value, they work on a contingency basis, meaning you can hire an attorney without paying any money until the matter results in a positive outcome for you. Many advance all the costs of the litigation as well. Do not let fear of fees and costs keep you from finding a good attorney.
Good luck to you.
