European Union – Employment. Clause 4.1 and 4.2 of the Framework Agreement on part-time work did not preclude national legislation which, in calculating the amount of the occupational pension of an employee who had accumulated full-time and part-time employment periods, determined a uniform rate of activity for the total duration of the employment relationship, in so far as that method of calculating the pension did not violate the pro rata temporis rule. The Court of Justice of the European Union so ruled, among other things, in a preliminary ruling, in proceedings between an employee and Mars GmbH, regarding the calculation of the amount of the employee's occupational pension.
