One of the best ways to hold on to your best employees is to give them appraisals or benefits for their outstanding performance. This is the most important aspect of employee performance management for supervisors. This is also what exactly Google did to prevent its top guns from joining Facebook. Lots of employers today, offer performance reviews to appraise the work of existing employees. Performance reviews give evidence to an employer, who can then conclude if an employee will get an increase, a promotion or a bonus. A poor performance review can cause the termination of employee's job. State or Federal laws regulate worker’s performance appraisal reviews or there are some laws associated with the same.

Accessibility
State law requires employers to give access to performance reviews of ex employees. It will require the employer to keep the performance appraisal records for some years. As per the State of California, for example, several employers are required to retain work records at the office, make the documentation available in least possible time period or let the employee to check the work records where they are kept.

Disability
Staff members with a disability have privileges that are associated to employee performance reviews. Based on the Equal Employment Opportunity Commission, a company may still relate all production actions to a staff with a disability. But, a disabled employee has civil liberties to practical accommodations which are essential while performing their job activities. The company may not terminate these reasonable adjustments because of a poor performance appraisal.

Optional Reviews
Private companies do not have a legal commitment to organize employee performance appraisal. As per the Department of Homeland Security, an employer holds a liability when managing a performance review of potential favorite candidates. Also, a company who does not conduct performance appraisal can fall into a legal trap because a lack of performance review can imply that the employer did not try to assist the progress of an employee in his job performance. Any performance review standard must specifically be based on the job performance of the staff, or moderate all employees as per central similar standards.   

Required Reviews Many employers have lawful obligations to carry out employee performance reviews. Federal agency, as well as universities or state agencies, may be needed to perform these assessments. Federal laws denote the necessary aspects of a federal employee performance review. Based on the Department of Justice, these codes comprise regulations which need the storage of these records for a time of four years or at the same time it requires that the agencies provide alternating reports when essential, such as provisional reviews.
