As with any Torah prohibition, one may not speak rechilus even when he was asked to do so by someone who will be upset by his refusal to comply and has the power to do him damage. One must be prepared to suffer embarrassment, jeopardize his social status, or even lose his job in order to avoid speaking rechilus.
As with other forms of forbidden speech, one may not speak rechilus upon the request of a parent, teacher, or rav, except when it is necessary l’toeles, for a constructive purpose (see below).
