GC_H4+EAD Future employer

[usa@2008]

Hi All, 

I have filled my Green card process with Company A as FUTURE EMPLOYMENT and i am currently working with company B.

under the process of my GC, my Labor &  I-140 is approved with my Future employer Company A, now, i have filled H4+EAD for my spouse and its been 35 days.

Now, my question is,  if my spouse H4+EAD approved, can she work with any employer ? and my H1B is currently holding with Company B, but GS process is going with Company A. 

Any issues to work on H4_EAD ? due to H1B holding with one company and approved H4+EAD is holding with different company. 

Thanks for all your input.
