Strikes are not the answer except I'd go so far as to say a sit-down strike has some effect on management without 1/harming the pocket of the worker and 2/harming the business.

I'll never forget around 1966/67 when there was some protracted wage negotiations at Rolls Royce, a union representative (it might have been the convenor) came back from a meeting and told us that a member of management had said "You're pricing yourselves out of a job, we're going to automate you."

After that, the first (primitive!) computer controlled machines were brought in. Although there were already mechanical automatic machines at work, the new machines were capable of more complicated jobs enabling one person the "look after" several at once.

Today? What do we see? Some absolutely amazing machines producing incredible work and they don't stop to chat to their mates about football/horses/gambling, take umpteen tea breaks or slope off the read the newspaper in the toilets for half an hour!!!
