<human>: Can you provide a brief overview of the text?

For starters, I work for a major shipping company as a part-time supervisor. 6 months ago I was moved from a area I know very well to another area I know very little about in my job. The reason I was moved is because someone was quitting and my boss felt that no one else would be able to handle the responsibility and get the results he wanted like my predecessor did. Anywho my first 2 weeks I was getting trained by the quitter(until his 2 weeks was up) and another coworker who helps out(hes been there for a year), well call him Alex. After the guy finally quit, Alex and I decided to split the work 50/50. This went extremely well for the first 5 months up until after our peak season, corporate decided to cut everyones hours by about 2 per day. Alex got extremely upset and started slacking on his portion of the work. Small amount at first until last week im basicly doing ALL the work. Im entirely OK with this part because he wasn't very reliable to begin with plus part of my job is audit all our paper work so If I do it all I know there aren't any mistakes and overall I do less work; BUT, many of our employees are noticing hes getting lazy and they are starting to vent to me about it. Part of our job is to help them when it gets tough and Alex just gives no fucks about them so im the only one helping which pisses me off a little bit but not much. Its getting to the point where they are calling him out in front of me and saying, and I quote, "You don't even do anything, Pacattack57 does all the work anyway." Now I completely agree, BUT I really don't want to damage our coworker relationship to the point its awkward. I spend far more time with Alex than I do with my employees, but im not sure how to get him to do more work. PLEASE HELP :(
<bot>: Coworker is getting lazy and our employees are calling him out and saying im better than him with both of us present. Don't know how to get him motivated without damaging our work relationship.
