On-demand workers (tarvittaessa töihin kutsuttavat) The employment contract can be written so that the worker is an on-demand worker. This means that the worker agrees to come to work only when called. If the worker only comes to work when called, each working period is a separate fixed-term employment relationship. Each of these periods must be legally justified. If the employer really needs a worker all the time, this type of contract is illegal. The worker then has the right to refuse the offered working periods. If the worker’s shifts are listed in a roster and the worker can not refuse to do the shifts, this proves that the worker is really a part-time worker, and minimum working hours must be agreed in the contract. For a real on-demand contract, all four of the following criteria must be met Each shift is agreed separately with the worker The worker has the right to not take a shift The work is not regular (not every day or every week)
