I am an articling student who was offered a hireback as a junior associate at my current firm back in January. I would be set to officially start sometime mid-summer following my call to the bar. However, I have not yet received anything in writing, and I accepted the position with a verbal handshake agreement in a closed room with my principal, without anyone present. He has since informed the other employees that I will be staying on. My principal has promised me via email that incoming work will eventually be assigned to me, though I have no written guarantees for anything beyond that related to my role. What options are available to me regarding potentially not proceeding with this anticipated position?
