frustration

I have this family I have been working with for close to a year. We have asked them to take care of the family's children. They have agreed, but manage to sabotage our efforts along the way. We have used interpreters so as to be clear what the expectations are. They have indicated agreement and understanding. This has been a frustrating process for all, no doubt. Yesterday, I found out the resource had not been truthful with me, with the other agencies involved or with the other social workers involved in the case. Today I have to close this case, with the knowledge that there is a very good chance that this will come back very soon.
