All contractors, vendors, and consultants must assure that their subcontractors abide by the City's Human Rights Ordinance. The City's protected classes are listed at Iowa City City Code section 2-3-1. CC -1 SECTION II - ASSURANCE OF COMPLIANCE The following sets forth the minimum requirements of a satisfactory Equal Employment Opportunity Program which will be reviewed for acceptability. PLEASE RETURN PAGES CC2 AND CC3 OF THIS SECTION TO THE CONTRACTING DEPARTMENT PRIOR TO THE EXECUTION OF THE CONTRACT. With respect to the performance of this contract, the contractor, consultant or vendor agrees as follows: (For the purposes of these minimum requirements, "contractor" shall include consultants and vendors.) a. The contractor will not discriminate against any employee or applicant for employment and will take affirmative efforts to ensure applicants and employees are treated during employment without regard to their race, color, creed, religion, national origin, sex, sexual orientation, gender identity, disability, marital status, and age. Such efforts shall include, but not be limited to the following: employment, promotion, demotion, or transfer; recruitment or recruitment advertising; layoff or termination; rates of pay or other forms of compensation; and selection for training, including apprenticeship. b. The contractor will, in all solicitations or advertisements for employees placed by or on behalf of the contractor, state that it is an equal opportunity employer.

How does your business currently inform applicants, employees, and recruitment sources (including unions) that you are an Equal Employment Opportunity employer? The above responses to questions 1 through 6, are true and correctly reflect our Equal Employment Opportunity policies. Business Name Signature Print Name Phone Number Title Date CC -3 SECTION III - SUGGESTED STEPS TO ASSURE EQUAL EMPLOYMENT OPPORTUNITIES 1. COMPANY POLICY Determine your company's policy regarding equal employment opportunities. Document the policy and post it in a conspicuous place so that it is known to all your employees. Furthermore, disseminate the policy to all potential sources of employees and to your subcontractors asking their cooperation. The policy statement should recognize and accept your responsibility to provide equal employment opportunity in all your employment practices. In regard to dissemination of this policy, this can be done, for example, through the use of letters to all recruitment sources and subcontractors, personal contacts, employee meetings, web page postings, employee handbooks, and advertising. 2. EQUAL EMPLOYMENT OPPORTUNITY OFFICER Designate an equal employment opportunity officer or, at minimum, assign someone the responsibility of administering and promoting your company's Equal Employment Opportunity program. This person should have a position in your organization which emphasizes the importance of the program. 3 3. INSTRUCT STAFF c') .. ..S s Ae l.a Your staff should be aware of and be required to abide by your Equal Employmerif- pportunity prQgram. All employees authorized to hire, supervise, promote, or discharge employees or are involved: in such actions should be trained and required to comply with your policy and the current equal employment opportunity laws. 4. RECRUITMENT (a) Let potential employees know you are an equal opportunity employer. This can be done by identifying yourself on all recruitment advertising as "an equal opportunity employer". (b) Use recruitment sources that are likely to yield diverse applicant pools. Word-of-mouth recruitment will only perpetuate the current composition of your workforce. Send recruitment sources a letter annually which reaffirms your commitment to equal employment opportunity and requests their assistance in helping you reach diverse applicant pools. (c) Analyze and review your company's recruitment procedures to identify and eliminate discriminatory barriers. (d) Select and train persons involved in the employment process to use objective standards and to support equal employment opportunity goals. (e) Review periodically job descriptions to make sure they accurately reflect major job functions. Review education and experience requirements to make sure they accurately reflect the requirements for successful job performance. (f) Review the job application to insure that only job related questions are asked. Ask yourself "Is this information necessary to judge an applicant's ability to perform the job applied for?" Only use job-related tests which do not adversely affect any particular group of people. (g) Monitor interviews carefully. Prepare interview questions in advance to assure that they are only job related. Train your interviewers on discrimination laws. Biased and subjective judgments in personal interviews can be a major source of discrimination. (h) Improve hiring and selection procedures and use non -biased promotion, transfer and training policies to increase and/or improve the diversity of your workforce representation. Companies must make sure procedures for selecting candidates for promotion, transfer and training are based upon a fair assessment of an employee's ability and work record. Furthermore, all companies should post and otherwise publicize all job promotional opportunities and encourage all qualified employees to bid on them. CC -4 + A, p '001 city0 , OT ■ C 7.
