Most employers expect much more of their employees than bare minimum effort, yet many themselves do the bare minimum or less for their employees in return. You can legally pay more than minimum wage and should if your expectations and requirements are more than minimal. Excellent employers provide more benefits than the minimum required (e.g. tuition reimbursement, bereavement leave, retirement plans, generous vacation and sick leave policies). Some companies are struggling and can't afford to do as much, we all understand that. However, don't expect excellent employees to join such a company or, if they do, stay with a sinking or struggling ship for long.
Who wants to be a continued patron of a store that provides the bare minimum of customer service? Likewise, who wants to work for an employer with that same bare minimum philosophy toward its employees? Provide a place of employment to believe in and to get excited about. "Just shut up and do your job" will net you much turnover and also the legal problems such a philosophy deserves. Rarely does an excellent organization get sued relative to a bare minimum one, an extra bonus. When outstanding employers make mistakes, they rectify them promptly and appropriately. They don't tend to engage in years of pointless and expensive litigation.
If we all only do the least we can, we shouldn't expect much in return, in any aspect of life. "Do more, be better" is a two-way street in the employment world. http://www.employmentlawman.com/monday-morning-musings.html
