Dortmund have't told Schulz not to come in to work, nor have they said anything about suspending him. All they have said is that they have held talks with the players and his representatives, which is precisely what any self-respecting company would seek to do if one of their employees was subject of such serious allegations. He can try and "sue the arse" off of them for having a conversation with him and his team and he'll be laughed out of court, even if found innocent. You clearly haven't bothered reading their actual statement properly and therefore clearly don't understand the argument I am making.
Their statement concludes with the following:
As this is a pending case in its early stages, and the factual and legal situation is extremely unclear to Borussia Dortmund as it stands today, we are not yet able to make any reliable and legally watertight decisions with regard to labour law and disciplinary measures. However, we reserve the right to do so at any time once we objectively know more.
I'm not sure what your ongoing issue with this is. Dortmund are handling this impeccably. They have responded swiftly, firmly but fairly. Have refrained from taking any decisions that may be legal in nature, and have given the player and his team the chance to explain his side of the story.
Arsenal by contrast have done **** all and I find it mystifying that you continue to defend the indefensible.
