Everyone has a right to withdraw labour. It is the only way the masses have achieved a fairer deal and ensure those in a position to use them to create wealth do not go too far and abuse their workers.
Complaining because of inconvenience is inappropriate, especially since there are two sides to any dispute and it is unreasonable to push all the blame for a strike on those who felt they were left little option. It smacks of, "I'm important, should not have inconveniences in life, the rest of you are not and should put up with whatever state you find yourself".
If one wished not to lump a number of complaints together as if it made a case and discussed each separately, then there may be something worth investigating.
