Organizations typically have some sort of codes of conduct or respectful workplace policies, says Valerie P. Keels, the head of D.C. office services at Gavi, the Vaccine Alliance . She recommends that the person who has been yelled at refer to their organisation's policy (maybe asking HR for a copy) to identify which provisions have not been upheld by the yeller. Again, asking a supervisor or HR to help mediate is totally permissible, says Keels. Plus, you might even be helping to corroborate a pattern of bad behaviour with HR that needs to finally be addressed.
