No grounds for dismissals required in the laws reviewed. This does not result in a total freedom to terminate the contract: it must be understood in light of the existence of prohibited grounds.
For summary dismissals, important reasons are required: sec. 1162 CC. Are considered as "important reasons" those reasons relating to the worker's conduct or capacity (see sec. 82 Commerce Regulations, sec. 27 White-collar employees Act).
Under the Federal Equal Treatment Act (2004, as amended in 2005), are prohibited in connection with dismissals, discrimination on the grounds of sex (including marital and family status), ethnicity, religion, age and sexual orientation (sec. 3 (7) and 17 (1) 7)).
On pregnancy and maternity leave, see: Maternity Protection Act, sec. 10.
In addition, sec. 105 (3) 1) WCA provides a list of inadmissible reasons for dismissals: trade union activities (and assimilated : works council members, health and safety representatives..), absence as a consequence of military or civil service, filing a complaint against the employer (well-founded claims in respect of entitlement or benefits arising out of the employment contract).
When contested before the Court, the judge will assess the existence of prohibited grounds for dismissal or whether it consititutes an unfair dismissal (verpönte Kündigungsmotive or sozialwidrige Kündigungsmotive).
