Werken bij ProActive betekent jezelf zijn en je sterkste competenties inzetten voor een gezamenlijk doel. We werken met z’n allen in één grote, open ruimte. Hierdoor is er geen sprake van korte lijnen, er zijn namelijk geen lijnen. Heb je een vernieuwend idee, of andere input, loop je zo even naar ‘een andere afdeling’.

Wij verwachten veel van onze collega’s, maar stellen daar ook flink wat tegenover. Balans. Je doet mee in onze winstdeling en hebt de mogelijkheid om jezelf te ontwikkelen door trainingen. Daar investeren wij graag in.
