Section 10-2. Working hour arrangements

(1) Working hours shall be arranged in such a way that employees are not exposed to adverse physical or mental strain, and that they shall be able to observe safety considerations.
(2) An employee who regularly works at night shall be entitled to exemption from the working-hour arrangement that applies to the employee group if such exemption is needed by the employee concerned for health, social or other weighty welfare reasons and can be arranged without major inconvenience to the undertaking.
(3) An employee shall be entitled to flexible working hours if this may be arranged without major inconvenience to the undertaking.
(4) An employee who has reached the age of 62 or who for health, social or other weighty welfare reasons so needs, shall have the right to a reduction of his or her normal working hours if the reduction of working hours can be arranged without major inconvenience to the undertaking. When the agreed period of reducing working hours has expired, the employee has the right to resume previous working hours. Other conditions being equal, an employee working reduced hours shall have a preferential right to increase his working hours in the event of a vacancy in the undertaking provided that the post wholly or essentially is assigned the same tasks. A preferential right pursuant to sections 14-2 and 14-3 shall take precedence over a preferential right pursuant to the present provision.
