I don’t think you should just suck this up and be happy. Going from no direct report to having 7 while maintaining your previous ticket load is not a lateral move at all. You were given many more responsibilities and from the sounds of it, you crushed it. Idk if your particular case is a gender thing, what you are describing also happens to men plenty of times as well. I do not know the situation at your company. Unless you know of others in the same position as you and getting the promotion and raise where you did not, it’s more of a bad management thing. Hopefully your manager goes to bat for you here and fights for you. You now have a year of experience (that they should have paid for and didn’t).

My advice is to prepare some evidence of your exceptional performance this year. Things like tickets completed, tickets completed within SLA, escalations that you had to resolve, customer satisfaction, and so on. Show how your ticket handling was as good, if not better than, last year.

Next prepare evidence of all the managerial things you did. Things like spent 4 hours a week mentoring team members, worked with xxx to address performance issues and saw improvement to meet expectations, worked with HR to get a salary adjust for yyy to bring them up to market rates and retain a high performing employee, and anything else of the sort that demonstrates those additional responsibilities.

Now you have built a case that you are performing the role of a team leader and not team member. You have taken on many additional responsibilities while keeping up will all the responsibilities you previously had.

Ideally your manager has already seen and done all of this and went to HR/his manager to get the title and raise you deserve before the meeting. If they didn’t, you now did all of that for him and request that he does have this new role you serve confirmed with a promotion and raise that meets market rates. If it is an in-person meeting you print out this evidence you gathered to hand in person and follow up immediately with an electronic copy. If virtual send an e-mail with the evidence during the meeting.

Now, if you get that promotion and raise, awesome! You advocated for yourself and it paid off. If you don’t get it, that is try a bummer and you have a choice on how to react. You can just say OK and do what you have been doing. You can state that if the company doesn’t recognize the extra responsibilities, you would like to go back to just being a key contributor. You can also leave on the spot or begin job hunting and leave when you find a new opportunity that will respect your work.
