I work in two jobs. I was sent on unpaid leave by both workplaces, returned to work at one place of work, and was sent again on unpaid leave. What should I do?

You need to send to the Unemployment Department, via the website, a letter from the second employer indicating the expected period of unpaid leave. You also need to attach pay slips from the place of work to which you returned, specifying the number of working days.
There is no need to submit a new claim for unemployment benefit.
