1) Courts disagree on the proper legal standard to apply in retaliatory hostile work environment claims brought by employees against their employers. Some courts require the conduct to be "severe or pervasive" enough to change the nature of employment, while others focus on whether the employer's actions produced injury or harm.
2) One key lesson from recent Pennsylvania cases is that courts reject claims based on trivial slights but will consider specific actions an employer takes that could dissuade a reasonable employee from filing a discrimination claim.
3) Lawyers should advise clients to remove complaining employees from retaliating supervisors, offer additional training or counseling to resolve disputes, and take other actions to diffuse tensions rather than risk viable retaliation claims
