(Part Five: The Code of Obligations)

¹ The con­clu­sion of a col­lect­ive em­ploy­ment con­tract, its amend­ment and ter­min­a­tion by mu­tu­al agree­ment, the ac­ces­sion of a new con­tract­ing party and no­tice to ter­min­ate the con­tract are val­id only if done in writ­ing, as are de­clar­a­tions of ac­ces­sion by in­di­vidu­al em­ploy­ers or em­ploy­ees, the con­sent to such ac­ces­sion by the con­tract­ing parties pur­su­ant to Art­icle 356b para­graph 1 and no­tice to with­draw from the con­tract.

² Where the col­lect­ive em­ploy­ment con­tract is open-ended and does not provide oth­er­wise, after one year has elapsed any of the con­tract­ing parties may with­draw from it at any time by giv­ing six months’ no­tice, which is ef­fect­ive for all oth­er parties. The same ap­plies mu­tatis mutandis to parties sub­sequently ac­ced­ing to the con­tract.
