405.02000: EMPLOYER INTERFERENCE, RESTRAINT, COERCION; THREATS OR PROMISES; Express or Implied Threats
Allegation that employer’s agent told probationary employee she “should not talk to anyone about the investigation” of a fellow employee’s complaint of abusive treatment against supervisor stated prima facie case of interference with protected rights, since, on its face and without further explanation, a directive not to talk to “anyone” could reasonably be construed to prohibit contacting union representatives, or enlisting the support of other employees for the complaint. (p. 22.) To the extent that an employer’s directive or policy of maintaining “confidentiality” of investigations into employee grievances “muzzles” employees who seek to engage in concerted activity for mutual aid or protection by denying them the very information needed to discuss their wages, hours or working conditions, it necessarily harms employee rights. (p. 21.) Once it is established that the employer’s prohibition on discussing wages, hours or working conditions adversely affects protected rights, the burden falls on the employer to demonstrate “legitimate and substantial business justifications” for its conduct. (21-22.) To overcome a presumption of invalidity stemming from a vague or overinclusive rule, the employer must make it clear to employees that the thrust of an inexplicitly-worded confidentiality rule is not to prohibit discussion of their terms and conditions of employment.

405.02000: EMPLOYER INTERFERENCE, RESTRAINT, COERCION; THREATS OR PROMISES; Express or Implied Threats
Employer statements asserting a right to influence or direct the employees’ choice of a representative are impliedly coercive, because they convey the impression that engaging in union or other concerted activity is futile. Allegation that human resources official told employee that she, rather than employee, would choose employee’s union representative for him constituted prima facie case of interference with protected rights. more or view all topics or full text.

405.02000: EMPLOYER INTERFERENCE, RESTRAINT, COERCION; THREATS OR PROMISES; Express or Implied Threats
A finding of interference, coercion or restraint does not require evidence that any employee subjectively felt threatened or intimidated or was in fact discouraged from participating in protected activity; rather the inquiry is an objective one which asks whether, under the circumstances, an employee would reasonably be discouraged from engaging in protected activity. more or view all topics or full text.

* * * OVERRULED IN PART ON OTHER GROUNDS by Trustees of the California State University (Northridge) (2019) PERB Decision No. 2687-H. * * *Both statement to union steward conducting union investigation into alleged misconduct by a supervisor for a potential grievance that she could find herself under investigation for impeding employer’s investigation and issuance of cease and desist order constituted at least “slight harm” to employee organizational rights. In balancing competing interests, interference with employee organizational rights outweighs business justification proffered by employer for its conduct. more or view all topics or full text.

Where charge alleged that the respondent offered suggestions regarding curriculum issues after “implying” there were student complaints regarding charging party’s teaching techniques, and where charge implied that such conduct was connected to a comment made to her by a union representative that she could expect “repercussions” from the school district if she pursued her grievance with a private attorney, charge failed to state prima facie case of interference; respondent’s discussion with charging party concerning the curriculum cannot objectively be found to tend to discourage charging party from exercising protected rights and unions and employers are not liable for each other’s conduct. more or view all topics or full text.
