It's not fun not having stuff to do. As you say it feels bad because you're not being useful and the time really drags too. I would suggest trying to get out of a job like that, use the time to learn something new or brush up your CV.I need to rant about a low workload! I love my job when I actually have tasks but half the time I have nothing to do. I ask constantly if I can help people and there’s normally a “oh all my stuff is complicated” answer. I’ve raised it with my bosses too and don’t get far. When I WFH I have so little to do and I feel bad about it!
