关于裁员计划的冲突
某机械设备厂上半年出现严重的亏损，年底还要还清一大笔银行的贷款。在实行了两个多月的节约计划失败以后，总经理袁斌决定紧急裁减百分之十的员工，并要求在各部门和各工厂将裁员的名单在一周内上交总公司。该公司的阀门厂厂长方明认为裁减计划不适合阀门厂。为此他与总经理袁斌发生了冲突。
方明："我认为我们厂应免于裁员。哪个单位亏损就让哪个单位裁员，这样才显得公平"。
袁斌："这次裁员是强制性的措施，任何部门和单位都不能够例外"。
方明："可是我们厂完成的销售额超过预期的百分之五，利润也到达指标。我们的合同订货量很大，需要扩大生产能力"。
方明："我知道你们过去的成绩不错，但你要认识到你们的业绩是和公司其他单位提供的资源以及密切的合作分不开的；况且如果每一个厂长或部门经理都象你这样找出各种理由，公司的减缩计划就不能成功"。
袁斌："但你的裁员计划会毁掉我们阀门厂。我不想解雇任何人，你要裁员就从我开始吧"。
方明和袁斌不欢而散。方明在考虑解聘袁斌，但又觉得无法向董事会解释原因，为此他感到两难的境地。你认为方明和袁斌的冲突是什么原因造成的？
