Aangezien romantische of verkerende relaties buiten de toezichtshiërarchie eveneens verstorend kunnen zijn en de moraal en het vertrouwen in de organisatie kunnen schaden, afhankelijk van de omstandigheden, verwachten we dat alle medewerkers die verwikkeld zijn in dit soort relaties om gezond oordeel te gebruiken, te handelen met discretie en zich bewust te zijn van iedere negatieve impact die hun relatie op hun collega’s kan hebben. Sommige van de vaker voorkomende gevallen van belangenverstrengeling kunnen zich voordoen indien u: • aan activiteiten deelneemt die ingaan, of lijken in te gaan, tegen de belangen van ons bedrijf • een persoonlijk of financieel voordeel krijgt van, een financieel belang heeft in, werkt voor, of diensten levert aan een bedrijf dat zaken doet met ons of met een concurrent of dat wil doen 22 Inhoudsopgave • uw zakelijke beslissingen laat beïnvloeden, of schijnbaar laat beïnvloeden, door persoonlijke of familiale belangen of vriendschappen - bijvoorbeeld wanneer bedrijven in bezit/onder controle van u of een familielid zaken proberen te doen met Avient • extern werk (inclusief diensten voor een Raad) verricht dat negatieve impact heeft op uw werkprestatie of strijdig is met uw verantwoordelijkheden aan Avient • bedrijfseigendom, -informatie of -middelen gebruikt voor uw persoonlijk voordeel of het voordeel van anderen • een familielid, inclusief schoonfamilie, of iemand waarmee u een romantische relatie heeft, aanneemt, er leiding aan geeft of als een directe of indirecte ondergeschikte heeft. De reikwijdte en impact van onze operaties, gekoppeld aan onze hoge ethische normen, vereisen dat we zeer duurzame oplossingen nastreven die de test der tijd kunnen weerstaan.

Companies acquired by Avient go through a rigorous EH&S integration process to bring new sites in line with our high standards and policies.
