Doing strikes in a piecemeal fasion are not successful

Another day of train strikes occurred today. I was on the 7:22 train and it came to a stop at 8am in Waiblingen, two stops from the Stuttgart train station. We were told that this train was stopping and there would be no more trains until 11am. Everyone got off, went to the Sbahn station, and eventually there was an announcement that there would be no more Sbahns. Then, we went to the bus station and figured out how to get into Stuttgart. At 8:30am there was an announcement that there a train would arrive and go to Stuttgart. Everyone trooped to the platform, the train arrived and we were taken to the train station.

I'm not certain how effective this is for the railroad workers' strike. If there's a strike, just go on strike and shut the entire system down until an agreement is made. Doing strikes in a piecemeal fashion are not successful.
