To create an accommodation request you go to Personnel management – Workers or Employees. From there you find “Accommodations” in the action pane under personal information.
Now the accommodations page opens and you can create a new accommodation for the employee. To create it you select the accommodation type, you could selet a Job task which makes the employee request the accommodation. When you first set it up, the accommodation is set as requested.
This is not something the employee is supposed to do themselves, but this is something HR is supposed to register.
