解析：考查条件句中虚拟语气的形式。条件句中的虚拟语气根据不同的时间有三种不同的形式：
时间
从句谓语形式
主句谓语形式
将来
动词过去式(be用were)
should + 动词原形
were to + 动词原形
would / should / might / could + 动词原形
现在
动词过去式(be 用 were)
would / should / might / could + 动词原形
过去
had +动词过去分词
would / should / might / could have + 动词过去分词
根据主句含义，他将会被解雇。可知从句假设的是在过去已经完成的动作，故用从句用过去完成时态。故选A，其他选项时态不符。
