Legal Question in Employment Law in California

No. Not of any kind.

A "case"??

No.

It sounds like you have a warning that your job is in jeopardy.

In general, unless an employee is civil service, in a union, or has a written employment contract, they are an 'at will' employee that can be disciplined or terminated any time for any reason, with or without �cause�, explanation or notice. Any employee's goal should be to keep their supervisors happy and make them look good to the company, and make the company money. That�s how the company pays employee wages. If you don't, then don't be surprised to be replaced.
