My question involves labor and employment law for the state of: California
I was asked by my company if I would be interested in a new position involving more responsibility and a physical relocation to another state (New York). I responded in writing that I would be interested but only if I would get promoted to the next level.
The Head of the NY office called me and asked me if I would move to NY at my current level. I politely declined and responded to him in writing that such a move would be financially costly and difficult from a family perspective and that I could not justify it unless I would get promoted.
He called me back a couple of days later and asked if I would accept the position if I receive a commitment to get promoted to the next level within a year as they first had to upgrade the position to that level.
I wrote back to him and told him that I would accept this position and the move provided the commitment to be promoted within a year at the latest is agreed upon by all concerned. I copied my communication to the company`s sr. management.
The head of the NY office simply responded in writing "all right". In a follow-up verbal communication, sr management confirmed in unambiguous terms (used the word "promise") that the promotion will materialise within 12 months.
Based on this commitment i moved to NY. 12 months have passed and the promotion has not materialised although the position was upgraded. Upon sending a reminder, the new head of the personal department now denies that a commitment was made. Do I have legal recourse assuming I can unambiguously proof that the promise to get promoted to the next level by sr management of my company within a year was made?
