This person should have a position in your organization which emphasizes the importance of the program. 3.

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, trap4fer 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 tryi ing 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.
