As a US student, I have a slightly different complaint about strikes. Given the 80% attendance requirement put on all international students, I'm not in an equal position to UK students to participate. That means I can't miss more than around sixteen days of instruction. That includes sick days, unforeseen circumstances and supporting strikes.
I'm faced with two bad choices: crossing the picket line to fulfill attendance requirements or risking deportation. Even if the strikes don't last sixteen days, what if I were to get injured later in the year? With PEC forms being notoriously difficult to provide evidence for, I can't depend on University services to excuse my absence.
However, I don't blame striking lecturers. The attendance requirement is clearly a tool the university uses to prevent students from supporting strikes. While I won't put my visa status on the line for strikes, I still believe that UK students should not cross the picket line. Why be afraid to take a risk when you have nothing to lose?
