What are the effects of strikes and, in general, slowing down how quickly corporate objectives are met, and is it sustainable in the long term? Not exactly an economist here, though I'm interested in economics.

I'm thinking of the US Postal Service (the speed of mail delivery is slowing down), and locomotive engineers who are periodically refusing to report to work for safety reasons. What would be the effects of a widespread "go slow" from multiple industries?<br><br>Edit: Thank you for these thoughtful responses.
