Iowa Admin. Code r. 11-71.3
71.3(3) Employee solicitations. Employee solicitation is to be conducted using only methods that encourage voluntary giving. Actions that do not allow for and encourage free choice or that even create the appearance that employees may not have a totally free choice to give or not give are absolutely prohibited. This should in no way be interpreted as restricting the need for an effective, well-organized education program for employees. All employees will be given the necessary information to make an informed, free-will decision. Group meetings for this purpose are permitted. Employees may choose to attend or not attend such meetings.
Employees shall be free to publicize their gifts or keep them confidential. Individual employee contribution records are confidential records in the meaning of Iowa Code section 22.7(11).
