LABOR ORGANIZATION.   A union. See § 7103(a)(4) which reads in part as follows: "labor organization means an organization composed in whole or in part of employees, in which employees participate and pay dues, and which has as a purpose the dealing with an agency concerning grievances and conditions of employment . . . ."

LAYOFF EMPLOYEES.   Right reserved to management by § 7106(a)(2)(A). Proposals assuring employment security for certain employees violate this right (9 FLRA No. 108 #2; 10 FLRA No. l , #3). Proposals prescribing the order in which employees are to be laid off (e.g., requiring that part-timers be the first to be laid off and trainees to be laid off before journeymen, 25 FLRA No. 9, ##30 & 31) also violate this right, as do proposed layoff ratios (e.g., requiring that an equal proportion of supervisory/nonsupervisory and part-time/full-time employees be laid off, 25 FLRA No. 83, #3).
