This is like a protest? It has nothing to do with bowling, right?
When I first read it, I thought of baseball.
Are you sure that people in all Ukraine use this English word? There is word Стачка. Besides there is word Забастовка of Russian origin but it is a common and clear word for each ex-Soviet person.
I can’t vouch for ’all the people’, but I personally understand it and it is found in dictionaries. In fact, http://sum.in.ua/ defines «забастовка» as ‘same as страйк’.
