Been taking a career break of 1.5 years for mental break and decided to get back to the workforce. Will there be any concern(s) from prospective employers beside knowing what I did during this period?

Yeah, employers might have a few questions. The main one would be, "What did you do during the break?" Since you didn’t take any formal courses, you can talk about how you stayed engaged through reading and volunteering. It shows you were still learning and contributing in meaningful ways.

​

They might also wonder if you’re ready to get back into full-time work. Just be honest—share how the break helped you recharge and that you’re motivated to start fresh. Most employers just want to know you’re committed and ready to go.

Are you going back to the workforce at lower/same/higher pay grade & expected salary?

If it is at the same or higher than when you left, then you need to prove that the break helped you grow in whatever sense.

If it is at lower grade, then answer in terms of willingness to relearn?

BTW, it is commendable you did volunteering during the break! Instead of nua-ing the entire period.
