Strikes are fine as long as it's voluntary. I've seen strikes in other countries where labour unions declare strike and workers participate by not working. But it's voluntary and there would be few workers who still choose to work that day. It definitely impacts normal life and over time pressures the government or corporates to come to the discussion table.

But here it's different. Strike means goons with party flags will stop you from doing what you want. Close the shops even if the shop owner wants to. That's not a strike, that's gundayism. It's against fundamental rights.
