Changes of status, creating different forms of connectivity based on unnamed contracts of commercial law and transfer of business activity to third parties on other grounds are the ways in which employers can adapt to occurring changes. However, they can have a negative effect on the status of employees who have been rehired from previous employers. Therefore, the Labour Law confirms that: the new employer is to take over from the previous employer the general act and contracts of employment, valid on the day of the change of employer; the new employer is to apply the accepted general act, for at least a year starting from the day of employment change, unless determined otherwise; both the former employer and the new employer is to notify trade union representatives at the former workplace of the changes, and in cooperation with them undertake measures to alleviate any economic or social effects produced.
