Question

Hello Rabbi,
I started a job, and the boss told me: trial months, and then a permanent contract. Fine. I worked really well during those months, the boss was very impressed, we finalized a contract, and I worked another month. But then I suddenly feel like a total sucker. I’m definitely more hardworking than the veteran employees. We’re kind of technicians doing customer service on a somewhat complicated system, and everything is logged—how many service requests each person handled, where, and all the information. I’m in first place. The boss compliments me and is very pleased, but what exactly am I killing myself for? What’s wrong with being in fifth place???
Now I’d happily just match the lazy veterans, but the problem is that I don’t know—maybe I’d be getting myself into trouble here, because during the trial period I worked like crazy, and they signed me based on that. So if I slow down, is that like stealing? True, he could fire me, but that would be a hassle for him, and he probably won’t do it if I’m not first but fifth. But still, it’s kind of not what I presented to him. I’m the only one who had a trial period; all the veterans were apparently hired all at once. Maybe the boss understood that he has workers who like to sit around more—but why is that my problem? Why should I work almost twice as hard for the same pay as some random guy who started before me and now sits around half the day surfing Facebook?
