I don't have anything in writing with my boss. He called me on a Monday in Oct and I started on the Friday of that same week. I know that it says that a letter of intention to return to work 4 weeks prior can be written, but my boss asked me to come back. I did contact family Tax benifit so they knew that my Estimated income would be changed. they would have a record of that. Even if I did come back early, I will have worked 1 year continuously and so far that is all I can see that needs to be done.
