Got demoted after announcing my pregnancy

Timing is everything in retaliation/discrimination cases, and two weeks is suspicious enough that a plaintiff's attorney will pay close attention. Pregnancy discrimination under Title VII / PDA / state laws covers BOTH outright firing and adverse actions like demotion, schedule reduction, pay cut. Steps now: (1) don't sign anything. (2) Document the demotion in writing — ask the employer in writing for the reason. (3) File an EEOC charge (free, online, 180 days from the adverse action; 300 days in CA via DFEH/CRD which is the same agency for practical purposes). (4) Consult a plaintiff's employment attorney — these cases are often contingency-fee. Strong cases. Save your medical records (showing pregnancy disclosure date) and your performance reviews (showing prior good standing).
