This is not a strike but it has a similar characteristic, of group benefit.

If people working in the software industry work less, it helps other people in the software industry.

This argument uses the assumption that work done is linear with time spent working. Some people won't agree with this, but the founder of HN argued[1] that

> . . . real work needs two things errands don't: big chunks of time, and the right mood. . . . There may be types of work that can only be done in long, uninterrupted stretches, when inspiration hits, rather than dutifully in scheduled little slices.

In the simplest case, people work X% less time and receive X% less in total compensation. These people are still just as valuable to their employer.

Due to requiring the same total amount of work, new workers are hired. If they are less efficient, they are also paid less, and so the decision of existing workers to work less does not negatively affect the company.

However, in aggregate, more people employed means fewer people looking for jobs. This pushes wages up.

Result, more people employed in the industry and higher wages for everyone.
