Verdi recognised that the BVG had made concessions with the 24-month contract term. "Nevertheless, the overall package is not enough to adequately honour the hard work of the employees," emphasised chief negotiator Arndt. After several days of discussions with the employees, the bargaining committee has now decided to increase the pressure ahead of the next round of negotiations by taking further industrial action. This is scheduled for next Friday, the day after the warning strike. If no agreement is reached again, the conflict could escalate further. In this case, Verdi has announced a ballot for indefinite strike action. At least 75 per cent of participating members would have to vote in favour. The longest industrial action to date lasted over 48 hours. Significantly longer periods would be possible following a ballot.
