No, they wont as long as they get the current normal contracts based on the lufthansa general contract (Konzerntarifvertrag). Future contracts could be different and as far as i know there are allready some talks between the pilot union and condor management about that.
Will be interesting in the next two years since most german airlines at the moment have a real problem with their crewing levels, mostly due to inferior terms and conditions compared to other airlines who do operate out of and into germany.
