Feeling demotivated due to pay differences and undervalued
Hi, I work in CRO that was spun off recently from bigger Lab, recently I'm seeing my coworkers and previous friends are migrating to new orgs with atleast 30-40% hikes and I'm kind of underpaid for my experience (joined a lower role). This makes me compare with them and feel bad, I feel I have so much potential and can contribute more but my manager and scope of work here doesn't permit me to do so, I feel struck doing the same monotonous activity everyday and it's been atleast six months since I learnt anything new here.
The worst part is I am being made to do all the heavy lifting, all manual review part is allocated to me only, the other members get the programmed checks (reason being I'm more proactive and trustable). I don't feel valued enough or appreciated enough for my contributions nor am I given more responsibilities considering my skills.
It's been a year since I joined here, I promised my interviewer that he can trust me I will be here for atleast 2 years, also I don't want to hop within 1-2 years.
Please help me Seniors have you felt this way, what would you do if you were in my place.
