Employee's insulting behavior towards CEO justifies termination despite company interest protection claims.

The Supreme Court dismissed the employee's cassation appeal seeking reinstatement after his employer terminated his contract due to his insulting conduct toward the CEO. Although the employee argued that protecting company interests should excuse his behavior, the court found his public humiliation and undermining of management decisions constituted a valid cause for dismissal. The court ruled that such conduct violates social coexistence norms and damages the employer's reputation, outweighing any claim of self-interest.
