(Part Five: The Code of Obligations)

¹ Any clause in a col­lect­ive em­ploy­ment con­tract or in­di­vidu­al agree­ment between the con­tract­ing parties in­ten­ded to com­pel an em­ploy­er or em­ploy­ee to join a con­tract­ing as­so­ci­ation is void.

² Any clause in a col­lect­ive em­ploy­ment con­tract or in­di­vidu­al agree­ment between the con­tract­ing parties in­ten­ded to ex­clude or re­strict the prac­tice of a par­tic­u­lar pro­fes­sion or oc­cu­pa­tion by an em­ploy­ee or his ac­quis­i­tion of the ne­ces­sary vo­ca­tion­al train­ing is void.

³ The clauses and agree­ments re­ferred to in the pre­vi­ous para­graph are val­id by way of ex­cep­tion if they are jus­ti­fied by over­rid­ing in­terests that war­rant pro­tec­tion, in par­tic­u­lar per­son­al health and safety or the qual­ity of work; however, deni­al of ac­cess to the pro­fes­sion is not an in­terest that war­rants pro­tec­tion.
