My question involves employment and labor law for the state of: CA
So i was recently promoted, which included a 10% pay raise. I was annouced to the department on 1/09/2015, and I started my new duties last Monday, 1/12/2015. I went into my employee website to check on my status, and i noticed that my pay rate hadnt changed. So i sent an email wanting to make sure there were no issues. i was advised that there were some issues becasue the approval was sent so close to payroll, and that they are working on it.
So my boss comes up to me today, and says that my pay raise wont be applicable until Monday, 1/26/2015, and that basically she was sorry but there was nothing that could be done, they cannot back date it and there was an error because the change was submitted to close to the new pay period. I told her this was not acceptable, and i already started my duties. I told her that i have received unplanned bonus incentives, and that i know soemthing can be done to compensate me. She said she would see what else she could do.
Is this legal?
