Job advancement/pay question

Hi guys,

Apologies if this isn’t the correct platform/subreddit for this.

I’ve been employed as a sort of junior sysadmin for about 2-3 years with the same company now and after studying for a networking cert I have been offered a full time jr network admin position with the caveat that I will act as a last point of escalation for the guy replacing me for any questions. I have been pushing for this for a while now and am very grateful to have been considered by the team im joining.

My concern is that when discussing pay my supervisor is going to be switching me over to salary- I make about 15k over my base hourly in OT and he has stated that I will essentially be taking a pay cut when I go to salary. While I am super happy to work with this team and get this on my resume that doesn’t seem right to me. Should I be worried/ push back on this position or pay? Thanks in advance
