The option to trade holiday hours (leave) for additional salary has been reinstated. In previous years this option, which is part of the “multiple choice model”, was not available due to the financial situation of the university. However, because our university had a large financial surplus over 2013, the option has now been reinstated. In practice this means you may trade a maximum of 38 hours (i.e. half of the 76 hours that you are allowed to spend on “extras” such as a bicycle) for extra salary. Please note that taxes will be deducted from this amount; in particular, if you benefit from the 30% scheme you may also use this option. See also this DUB article (in Dutch).
