Employers should behave ethically - ha ha! (Score 1)

Accept or don't, it's completely up to you based on how you feel about the relationship between employer/employee. I personally feel that it is the employer's responbility to demonstrate their level of obligation without needing to be manipulated by their employee. An employer that does not consider the value of an employee without be coerced is either a thoughtless employer or a disrespectful employer. Either way, I personally don't like working for that type of employer.

If you think you'd be the kind of employer that would milk your employees, rather than work ethically with them, then take the counter-offer.
