In my previous job at Omni Advocacy Services, I found it most difficult when I couldn't get contact with clients, because of course if I was working a little bit later in the day, they might be at work, they might have been busy, asleep, things like that, and that was my only really difficult challenge. But I resolved it by making sure I kept consistent contact with my clients, I always texted them or emailed them, updated them as much as possible about our services we were doing for them.
