2.5yo wont sleep for dad, help!

Hi all,

I have recently started back at work, first time working since before DD was born. I work 5pm-10pm between 3-5 shifts per week.
Since going back to work, DH is watching DD, or picks her up from my mums when he finishes work. (Usually gets there between 7.30-8pm) her bedtime is usually somewhere about 8-8.30pm on normal days.
Since I have been back at work, she pretty well refuses to go to sleep!! She chucks huge tantrums, wont listen to anything he says, wont follow instructions, refuses to lie down in bed, whether its her own or with DH, and will usually end up falling asleep JUST before I get home (about 10.15pm)
When I am home with her, for the most part she is still perfect going to sleep. Obviously some nights are different but that's normal.
I know she's having some separation anxiety because I'm actually working 2 jobs at the moment and am training in both so am working a lot more shifts, but for the most part that has settled down now, except for going to bed when I'm not home..
Poor DH is at his wits end because he doesnt know what he can do to help, and he's beginning to dread bed time when im not around because of how she acts. I have experienced it first hand too when she first started with the separation anxiety because she was acting like this CONSTANTLY.
We both need advice on how to handle this and what we can do to help her go to sleep when I'm not home :(
I have a serious case of the mummy guilts because of how she's taking me going to work, and I feel awful knowing that she's acting this way because im not home.
Please help! :(

No experience regarding work, but the thought crossed my mind of having a goodnight phonecall with her at bedtime. Would that help?
Dd2 has terrible separation anxiety from me at night when she wakes and I'm out. Makes having a night off difficult :/ so I understand that side of it.
I hope she finds a new groove soon and realises daddy is -almost- as good as mummy ;) and that mummy always comes home after a while.

My DS was like this when I first went back to work. Unfortunately it just took time for him to settle into the new routine.

Hope things settle for you soon. It certainly does make it harder :(
