A typical day at work would always be a problem solving of issues on a flight, manpower issues ( sick calls, dealing with employees personal household problems ) and meeting and addressing few issues on the ramp with airline representatives or station manager. Learned a lot of things on my own specially dealing with union employees, did encounter a few issues before and got a little bit of support from the company. In other words CYA, and a little bit of help from the upper management would have been great if anyone is around. I don't think there is a hardest part of the job, it just depends on how a person deals with it and the approach he or she uses towards the issues or challenges. Everyday and moment is always a joyous part of our job, it just depends on how one person deals with and looks at it.
