Onder het motto ‘Scherper, Slimmer, Schoner’ is CSU vanuit 11 vestigingen landelijk actief in de schoonmaakbranche. Voor diverse sectoren, waaronder zorg, onderwijs en kantoren, is CSU al 55 jaar een gespecialiseerde schoonmaakpartner. Waarbij onze 15.000 collega’s het verschil maken. 


•	Scherper. Slimmer. Schoner. 

Om werk- en leefgeluk iedere dag weer een beetje beter te maken, innoveren we. Zo zijn we scherper, slimmer, schoner. Scherper op de kansen van morgen. En altijd bedachtzaam of iets slimmer kan. 


•	Een mensgerichte organisatie met een vaak verrassende en innovatieve aanpak

Wij hebben een scherpe visie op de ontwikkeling van schoonmaak en lopen voorop in de vernieuwing en verduurzaming daarvan. Steeds streven we ernaar om samen slimme manieren te vinden voor facilitaire vraagstukken van morgen en overmorgen. Daardoor realiseren wij de positieve impact voor onze mensen, klanten, het milieu en de maatschappij. 


•	Door en voor onze mensen

Een gezonde, gastvrije en gelukkige werkomgeving creëren. Dat begint bij onszelf. We investeren daarom in onze medewerkers en voeren een diversiteits- en inclusiviteitsbeleid. Zodat iedereen zich gewaardeerd, uitgedaagd en geprezen voelt. Dat is volledig in lijn met hoe onze oprichter Cor van der Heijden het in 1968 voor zich zag. 

Nu, jaren later, is CSU is een familiebedrijf waarin ook de directie en het management voor 1/3 participeert. CSU kreeg de Koning Willem I Prijs 2020 uitgereikt door koningin Máxima, een prijs die tweejaarlijks wordt toegekend aan bedrijven die uitblinken in goed ondernemerschap.
