human resources discussions

There are two questions which need to be done, they need to be lengthy and need citiations. No Plargarism.Discussion #1Explain why unions often place a priority on seniority in personnel decisions, whereas employers tend to emphasize ability to perform the job.Based on your own experience with work-performance appraisals conducted by managers, how confident are you that managers can effectively judge legitimate differences in performance between two or more employees? Please use a minimum of at least one source to support your post.Discussion #2Several alternative work schedules (e.g., part-time, flextime, compressed work week) are offered by employers. What would be your ideal work schedule? How likely are you to achieve that work schedule in the career you currently have or intend to pursue upon completing your education?  Use a reference regarding work schedules to support your discussion.
