This phrase suggests someone is being retired involuntarily, not by their own choice.

Forced Retirement

May imply a subtle way of removing someone from their role without a direct dismissal.

Discreet Dismissal

Can convey a negative feeling as it is undervaluing someone’s ability due to age or change.

Emphasizes discontinuing something that has become out-of-date or no longer efficient.

Often associated with technological changes where new innovations replace the old.

The process can be gradual, not necessarily an immediate action.
