公司准备跟我签departure mutual agreement , The agreement should be kept confidential. and pay attention to the terms that are not very obvious.
公司补付我没有修的假期, Not sure if this is a plus - they must do this anyway.
每周一天供我找新工作, While this is supportive, the critical thing is, you need 2~3 months to QI LV ZHAO MA.
平时也支持我找新工作, this is a soft term, but with this, they should not speak bad of you.
当有用人单位向公司咨询我的工作情况时,公司不说我是被 fired,
What is your company policy? They probably are not allowed to say this any way. Try if you get an official notice of lay-off.
我需要一个律师作为见证人,律师费公司出, Not sure if this helps much. Once you signed an effective agreement, it has a legal power.
Just 2 cents.
