The preparation and revision of job descriptions is a dreaded task and often forgotten or put on the back burner.  Don't underestimate the importance of job descriptions.  They can be used to describe open positions for hiring purposes, help determine whether a position is overtime exempt or not, as a basis for performance appraisals and raise determinations, determining essential functions and part of the reasonable accommodation(s) dialogue and more.  They are only useful if they are accurate, reviewed by legal counsel and revisited for accuracy from time to time.  A common mistake is to prepare job descriptions once and never review them again.  Job expectations can change over time.  Don't wait until your company gets sued to realize the importance of accurate job descriptions.  Again, preventative law is the key.  Take the offense, don't just play defense.

When was the last time your employee handbook was reviewed by a qualified lawyer?  If you can't even remember, it's definitely time for a review.  A well-written employee handbook is an invaluable tool, badly written your worst enemy.  They are not one-size fits all.  Be sure to have it reviewed for legal compliance on a regular basis (once a year is a good rule of thumb) because employment law is constantly changing and certain employment laws vary by state and even by city.  The Employment Law Man has prepared and reviewed numerous handbooks for over two decades and can help you with this dreaded but important task.
