 ## Proposed Changes
 
+### Descriptive
+
 * Allow description of the WP to updated.
 * Allow WP Issuer ability to retire WP
 * Possibly allow Committee to retire inactive WP
 
+### Technical
+
+* Add bool field `removed` to worker object.
+* Add check to `db_maint.cpp` to skip workers in removed state.
+* Don't allow votes to workers in removed state(`account_evaluator.cpp`).
+* Create operation `worker_update`. Op will allow to change only the `name`, `url` and the `removed` object fields from the worker (track the change in operation). Can follow `committee_member_update` or similars.
+* Implement new operation as a command to `cli_wallet` available for the worker issuer.
+* Allow `committee` to use `worker_update` against any worker proposal. Need more discussion on how it can be done.
+
+Requires hardfork.
