How long is too long?

Have I overstayed my welcome? Hours are getting stretched because there’s not enough people to cover the shifts. Sometimes we struggle to cover lunch breaks. We spend a lot of time running around like headless chickens and queues can build up quickly if someone has a complicated problem. We aim to give quick service to everyone, but we have to think about everyone’s experience so we might have to leave customers to conduct their own enquiries. I often think that me leaving would free up more people. I’m effectively doing the work of at least two people. But I’ll be out of a job and they’ll lose a lot of experience. Perhaps I’m selling myself too cheaply. I’d like to break away but I need to prioritise the time to do it, especially when the processes are becoming more and more ridiculous. I need to find my passion and inspiration to create some time to make it happen.
