Are you betting that there had to be a breach?
Under the contract Hauck had the right to terminate early, but the contract has an automatic liquidated damages clause, with exceptions if the early termination is for retirement, death or disability.
There did not need to be a breach for the liquidated damages provision to apply. It applies automatically because there was an early termination. The issue is simply the calculation of the liquidated damages.
At best 7 days of Bobby’s early termination was due to retirement, but the balance of the time left on the early termination of his contract is not due to his retirement. Whether he breached the contract is only relevant to the extent UM does not want to give him credit for the 7 days.
