Daughters Change in Her Behavior- Kind of a Vent.

I would never say to a mother "your child is acting up because you are working." However, you have a pretty unique situation which probably is hard on a three year old. I think it's not so much that you're not there as often, but rather that her schedule seems pretty inconsistent, different places and caregivers on different days, not to mention that being at daddy's workplace all day is probably pretty confining and dull for her.
Is there any possibility of sending her to daycare or preschool every day, or at least part or half time? That way she could get a chance to be around other kids and have fun, while you sleep and daddy works.
Cranky kids are usually bored kids, and that has nothing to do with whether mommy works or not.

Not only you working and not being around so much but also the change in routine. Kids crave routine, and when you mess with it, it throws them way off for awhile. Also, be sure you're still giving her some one on one time, including cuddle time. She may be having some separation anxiety by you not being as available as in the past.

She probably is reacting to the change in schedule, but she might also be manipulating you. You obviously feel guilty (as all working moms do) and she might be acting up to play off of that.

Give her some more time to adjust and try to make her schedule as consistent as possible.

Changes in situations will probably cause changes in behavior to some degree. Changes in AGE will also result in changes in behavior. It could be a combination of the two, or just her personality developing. Don't beat yourself up and try to "make up" for your schedule change in an unhealthy way. Try to brainstorm with your hubby and little girl so you can find new ways to connect as a family. Good luck!

I think it does have to do with working and I also think shes in the terrible 3s stages. She'll adjust to the routine eventually.

It's the change. She's reacting to the upset in her routine. Take a moment to spend with her and explain what is happening. It's important, no matter how young or how old, that you respect them as individuals who need an explanation. Most often as adults in our busy worlds, we forget that they really do need that. They thrive on the consistency of a routine. Just spend some time with her and explain why it's been disrupted. Good luck.
