Each year the company owner determines raises to go out to each employee. This year I accidentally read a memo addressed to HR that a lot of weight will be given to how "billable" an employee is. Basically, if you work 80% of your time on customer projects and 20% on internal work, you're likely to get a bigger raise than someone that only spends 50% of their time on customer projects.
Most of the employee are billable, but we have 5 that aren't because they only do internal work. They will be excluded from this rule. I'm an exception because I'm technically billable, but most of my work is internal, fixing IT issues.
Would it be better to approach my boss before I'm told my raise, because he decides the amount beforehand. Or, when I likely get a small raise, should I argue my case at that time? Raises are all decided beforehand so I thought it'd be better to talk to him before the meeting, but he would wonder how I found out about the new raise system.
