Puccini's La Boheme cancelled at La Scala in Milan

My mother is visiting me in Italy over the next two weeks, and I had planned on taking her to the opera at Milan’s La Scala.
I thought a nice evening out after work on a Friday would be just the thing, except that there was a little surprise for me on the website.

The Scala reports that due to a union strike, the performances of Puccini’s La Boheme planned for Monday 7th, Wednesday 9th and Friday 11th July will not take place.
I’ve never heard of this happening before, but had to devise a plan B quickly.

So we’ve decided to see Tosca at Verona’s Arena instead.
I’ve been once before but will give you some more detailed information on how to book tickets and what to look out for when you’re there – we’re sitting up in the stands dedicated to the plebs so I feel cushions are in order.

Both the Arena in Verona and La Scala in Milan have websites in English with information on bookings, how to get there and a map of the theatres.
