Had an awkward one on one call with my lead today.

I know I struggle sometimes to get my thoughts in order but they seemed to be genuinely concerned with my workload. Personally I guess yeah maybe, it's lighter most of the time but the times where it does get heavy it's nowhere near as worse back when I was the only other member of the support team, now I have two other team members to delegate tasks to now.

Currently I have excess time for build reviews and work on other tasks outside of routine maintenance/monitoring. They do tell me that I should delegate more tasks but outside of maintenance tasks and reviews I don't really do that much work? I can't really delegate review tasks yet since the new team members aren't familiar enough with the system for that. And honestly? I think I must slack off a minimum of 3 hours of work every day with the amount of dead air between tasks and have an aversion against unneeded overtime so I genuinely feel I'm not over working or anything. I guess there's the occasional weekend patches and maintenance but that's being rotated now between different team members... the biggest culprit I can think of is my last nightshift taking up to the afternoon of the next day because I was stuck in a round table for an incident adjacent to our system... I spent the whole weekend just sleeping due to that but my other night shift days are calmer than that forgetting what day it is aside.

Do I just have a problem communicating that I actually am fine with work or am I not reading enough into this?
