Assuming the position were to be salaried at $104k, a sensible agreement might be: - The employee is hired temporarily for a period of one to three months. - Their wage is paid weekly, at a rate of $2k per week (i.e. 1/52 of their expected salary) - The contract may be cancelled by either party with seven days' notice. - At its end, the contract automatically converts to a permanent position.
If a signing bonus is called for, it should be due early during the probationary period. A separate bonus for the transition from temporary to permanent employment may not be a great idea as it may incentivize the employer to terminate the agreement.
