The HR manager at a consulting firm notices a rapid increase in the demand for experienced leaders. The increase is making it difficult to hire managers at the same rate of pay compared to one year ago. The firm presently has three open manager positions and the three top candidates are demanding annual salaries higher than current managers’ salaries. This morning the firm’s CEO sent a companywide email announcing that staffing the job openings is a top priority to meet business demands. The email also indicated the firm is willing to pay a referral bonus. The HR manager knows that staffing the job openings will completely exhaust HR's budget, leaving no money to pay referral bonuses or make salary adjustments for incumbents. While reviewing the candidates' resumes the HR manager receives an email from an incumbent manager stating that the manager discovered the firm is offering higher salaries to applicants with less experience. The email also states the incumbent manager no longer trusts the leadership team and is going to seek other employment opportunities.

Which action should the HR manager take first to respond to the incumbent manager's email?
