You interviewed for a second time for a position with a company. In the interview you were promised, among other things, that you would receive a $3\%$ automatic raise after six months. However, when you get the job offer letter, which spells out the salary and benefits, there is no mention of the automatic raise. You had counted on that raise as part of your decision to work for the company but at the same time don't want to let this offer get away. Write an email to your contact in the HR department.
