Philippe LEMAIRE Philippe LEMAIRE Head of School RAVAGO in Drusenheim (67)

Since December1, 2018, our business has been sold to a European plastics group. With no HR resources on site, we turned to Boost'RH for support. Boost'RH was very responsive in offering us support within a very short timeframe, and our collaboration with Boost'RH is much appreciated by all our staff. Boost'RH shares its in-depth knowledge of SMEs with us, and is an integral part of our management committee. It's a real source of ideas and a great help in guiding us through this period of transformation. The introduction of the CSE and the negotiation of new agreements were a resounding success thanks to this weekly support, which can be flexibly adjusted to suit the moment. Philippe Caquet, head of Boost'RH, is also ready to listen and help us if we need it. I recommend Boost'RH. for his ability to make proposals, his excellent contacts, his flexibility and his energy.
