Coming from an employee who's looking to make some extra money on the side, I've got mixed feelings on this issue. On one hand, I've got a good income from my current company for the work I do. Although it's not enough to get me where I want to be financially, it's pretty close. I don't really have any reason to bail on this job to find another one. But on the other hand, I'm still looking to make more money. What's the best way to make money on a side gig? Do what you know - i.e. something in wide format printing & installing.
It's kind of complicated though. I don't want to jeopardize my current job, but this industry is my best bet on making more money. I do not feel ok with directly competing with my company, as I feel that would be dishonest. Soliciting clients to turn down all or part of our services so that I can do them independently is just wrong. Allowing customers to solicit my services outside of the company after they turned down the company's offer also seems dishonest. I didn't chase them down, but they're trying to undercut the industry - which also includes paying me less. But if I rummage up my own business, that's a different matter - so long as it's not negatively impacting my first job.
I've also thought about looking for a part time job with another company in the general print industry, like a wrap company. There are a number of different companies in our area who have more specialized fields, and would not be in direct competition with my current company. The bigger issue here is work hours. Most of them are open at the same times as my current job, so that's a bit tricky.
Anyway, I understand that this can be a complicated issue on both sides, and there are ethical tension points. But I agree that if he's not stealing business from the company and he's keeping up with his work, then I don't see the problem until it actually shows up.
