Am I allowed to go on strike?

My tax goes towards other peoples pensions but I don't have one. My self employment keeps me off the dole and gives jobs to other people too. If I am ill then I still have to work or I don't get paid. I get zero paid leave per year. Am I allowed to go on strike too? Is there ever a limit in this greedy modern world where people are being a tiny bit me me me when so many other people don't even have what they already have lined up.
