Many things may justify termination - poor performance, abusive or disruptive behavior, excessive tardiness and absences, among others. Employees also have the right to take family or medical leave, military leave and time off to vote or serve jury duty. Should you have legal grounds to fire an employee, be sure to document all the reasons and when they occurred, plus any disciplinary measures taken and the results (or lack of them). The employee also may be entitled to receive accrued vacation pay or sick leave in the final paycheck, as well as commissions, bonuses and unfulfilled company expenses.
