I suspect the BBC operates the same way as the Civil Service, which no longer deducts TU subscriptions from salary, so even if they wanted to, Managers do not know who is a TU member.
On days where there is industrial action, Managers take a record of those who haven't attended work. Furthermore, you don't have to be a member of a TU to take industrial action on the day of a legally balloted strike. Equally, you are not required to strike if you are a member of a TU.
In the Civil Service, leave is blocked on days where industrial action is called, but there is no requirement on people who call in sick to provide any additional evidence of their illness. I can't see why the BBC (or indeed any other employer) would operate a different policy, as it would be very difficult to enforce if challenged.
Managers can (and sometimes do) ask staff members if they're union members, but staff aren't obliged to answer. I don't believe managers have access to full payroll details to find out if they are union members. On a day of industrial action, they do make notes of who hasn't turned up for work so that pay can be deducted accordingly.

Once a strike is called, staff cannot apply for leave on that day. I'm not sure what happens if people call in sick - you can self certify as unfit for work for up to 5 days before a doctor's note is needed. But if you're genuinely unwell for work and it happens to be a strike day you might have to prove you were ill in order to keep your day's pay.
