Are you sick? Let the client know as soon as possible and cancel your gig in the YoungOnes app.
For temp gigs, a cancellation period of 96 hours (4 days) applies. Within that period you can cancel without consequences.
Can’t work at short notice due to illness? Tell the client right away. If you don’t show up without reporting sick or cancelling, the no-show policy applies.
Because you work via temp work, the rules around sickness follow the temp work conditions.
