My question involves labor and employment law for the state of: California

Hi,

I work for a fortune 500 company in California and my company wanted to me relocate (short term) to a different country for a period of 6 months and as part of the relocation the company had promised to pay me a one time bonus of 40000$ just to cover my US expense while I was away as my salary at the new location was less. I was promised that this bonus will be paid to me once I am back in US.

After completing the 6 months period when I returned back to USA and asked for my promised bonus, my manager initially said that the HR is still processing the request and now after two months, my manager says that the company does not have funds to honor this request. At this point I have not threatened any legal action and still trying to convince my manager that ethically and legally this is not right.

At this point, I have couple of emails and chats with my manager where he has mentioned in writing that the company will pay a one time bonus to me as part of the short term transfer. I want to know if there is any other documents that I should try to get my hands on to build a stronger case if I decide to take this legally.

Would really appreciate if any one can provide some guidance on what are my options here.
