Family Friendly Company

DPPpolniANGIn the context of an advisory - audit process it was estimated that the set measures introduced in the basic certificate were implemented and the goals were achieved, therefore Steklarna Hrastnik received the full certification. With respect to the basic certificate, the glassworks introduced 16 measures benefited by at least 80% of all employees.  In the context of the full certificate, 3 new measures will be added to the existing 16 measures.
Upon completion of the audit procedure, the auditor wrote the following: "During the audit, the appropriate manner of implementing the selected measures was confirmed. Although the number of measures was relatively high (16), all measures will be preserved in the next period. We want to welcome the fact that some of the measures have already been extended, taking into consideration the proposals of employees. Above all, we want to emphasize the commitment of the top management. It recognizes employee satisfaction as an essential element of effective implementation of the production processes, but also as a building block in increasing customer satisfaction and strengthening Steklarna Hrastnik Glassworks in a challenging market. I therefore propose that the organization Steklarna Hrastnik Glassworks receives the full certificate as a "Family Friendly Company".
