Job Change soon??? or not???

Hi everyone, I am glad that i passed the probation rather smoothly and can claim some allowance in due time. But now, the supervisor of my past company claims he can help me find work in his company. So now, my mind seems to be rather keen on a move back to my old company if he can really help me find a department that i can work in. So how long more will i be training in IMH library? A week more or longer? That i think will depend on how things go in the next few days...
