Alfred orally promised to pay Robert a salary of $30,000 per year for five years and his moving expenses up to $10,000 if Robert would quit his job and come to work for him at his manufacturing plant. Robert agreed to do so, but requested a written contract. Alfred assured him that the company attorney would prepare such a contract as soon as possible, but Alfred needed Robert to start at once. Accordingly, Robert sold his house, moved his family, and commenced to work for Alfred. He was fired without cause two months later. No written contract was ever executed. Can Robert enforce Alfred's oral promise?
