I have a question. I have 2 full time jobs. I am on leave from one job and still doing the other. I will be getting laid off from the the job I am doing right now because of shortage of work soon. I can’t go back to my other job because I on leave and the employer won’t let me go back until my leave is over. will I qualify for EI until either I can go back to my 1st job or until the 2nd job has hours for me.
