劳顾问:我单位经上级有关部门批准,最近将由集体所有制改为股份合作制。由于我单位是1996年8月实行全员劳动合同制的,单位与职工签订的劳动合同期限基本上是三年以上,现在改制后,管理人员的安排、工人的岗位必然要作较大的调整,原已签订的不少劳动合同已无法再履行,请问:这种情况是否允许单位单方变更劳动合同?望予指教,万分感谢!光强电子公司 Labor Advisory: My unit approved by the higher authorities, the recent collective ownership system will be changed to shareholding. Since my unit implemented the full-scale labor contract system in August 1996, the term of the labor contract signed between the unit and the staff and workers is basically more than three years. Now after the system reform, the arrangement of management personnel and the position of the workers must be greatly adjusted , Many of the original labor contracts have been signed can no longer be performed, may I ask: This situation allows unilateral changes to the labor contract? Looking to teach, very grateful! Light Electronics
