• 1 You could message the main thread to spawn another Worker thread. – Sebastian Simon Commented Sep 23, 2016 at 16:35

• 2 It should actually work, but it doesn’t work in Chrome and Safari yet. You could try the “detour” over the main thread as a work-around. – Sebastian Simon Commented Sep 25, 2016 at 14:37

For anyone who stumbles here, nested workers now have some support in Chrome at least: https://www.chromestatus./feature/6080438103703552:

Dedicated workers can create nested workers, but shared workers and service workers cannot.

Creating a nested dedicated worker from a shared worker is not yet supported.

Nested shared workers are also in the spec, but there is no plan to support them at this time.
