to three years in cases of access to particularly sensitive information. The employer must pay financial compensation for the duration of the CNC but the law doesn't specify anything regarding the amount of the compensation. Romania In Romania, CNCs are regulated by articles 21–24 of the labor code and restricted to two years. The employer must pay financial compensation for the duration of the CNC, amounting to at least 50 percent of the last 6 months salary.
