What are the causes of action brought by a plaintiff who was discharged for refusing to produce her employer's use tax returns?

the forced production of defendants returns or of the content of its returns. Plaintiffs right to recover turns only on whether she was discharged for communicating her reasonable belief that defendant was not properly reporting its use tax obligation. ( Haney v. Aramark Uniform Services, Inc. (2004) 121 Cal.App.4th 623, 641, 17 Cal.Rptr.3d 336.) The elements of her causes of action were alleged and can be proved without violating the implied taxpayer privilege.
