I see. Thank you for providing this additional information, Lloyd.
Since the company did not disclose the fact you would need IT technology training, that could provide grounds to allege that they misrepresented the position to you or even committed fraud.
If discrimination is not involved in your situation, which you have not mentioned as potentially explaining the employer's actions, then you would typically pursue this as a breach of contract or implied contract claim, or possibly fraud in seeking compensation for any injury you have sustained as a result of the employer's actions/omissions.
I would certainly retain a local employment law attorney at this point if the employer does not appear willing to negotiate or change their stance on this issue. The attorney could review your contract or other documents you have and make a final determination as to your best legal claims or communicate with the employer in an attempt to gain more information and aid in resolving this situation on your behalf.
The state and local bar associations can provide you with attorney referrals if you need one. The state's bar association can be found at calbar.org.
