Strong work group identities that encourage loyalty and self-censorship are barriers to whistle blowing.

Strong group identities can create a sense of loyalty and belonging, which may make individuals reluctant to report any wrongdoings or misconduct within the group. In addition, individuals may also feel pressure to conform to the group's norms and expectations, leading to self-censorship and the suppression of dissenting opinions. This can act as a barrier to whistle blowing.
