Article 60
Except in case of sickness or accident, an official may not be absent without prior permission from his immediate superior. Without prejudice to any disciplinary measures that may apply, any unauthorised absence which is duly established shall be deducted from the annual leave of the official concerned. If he has used up his annual leave, he shall forfeit his remuneration for an equivalent period.
If an official wishes to spend sick leave elsewhere than at the place where he is employed he shall obtain prior permission from the appointing authority.
