As David Schwarz says, it is not at all "impossible" to deal with dishonest employees who "continually claim 'skip-out' and pocket the money". They can be fired! It's not like it's impossible to notice if someone is doing this.

@André Borie: The thing is that vouchers like this are not valuable in and of themselves. There is no actual "waste" from them going to the trash. They have "value" only in the sense that they let you take things from the company that you would otherwise have to pay full price for: using them cuts into the company's profits; so from the company's perspective, misuse of vouchers falls into the same category as theft from the company. (The "would have gone to the trash otherwise" argument is flawed for other reasons related to incentives, but it's especially tone-deaf in this context)

Regarding the voucher misuse, here's a thread on a similar situation that might have some applicable advice: thestudentroom.co.uk/showthread.php?t=3323021 However, it looks really bad that you did this with 10 years of experience: after that much time most people would say you are expected to know better.

@Agent_L: There's a difference between doing something "without warning" and doing it without asking permission. The OP has given warning of the upcoming absence.

The OP said in the comments "medical issues, i MUST avoid alcohol, even a "tear"" which could I guess be interpreted to refer to alcoholism but doesn't sound like it to me.

@user70848: I've never seen the "don't show up too early" advice applied to 10 minutes. All the places I have seen that advice, it was presented as something like "don't show up more than half an hour early." But I agree with the first part of your comment: I don't think it would be a good idea to, say, ding someone for showing up "only" five minutes early unless they were explicitly told to arrive at least ten minutes in advance.

@bluegreen: There is also evidence that people prefer familar-sounding first names irrespective of the associated racial characteristics. See this blog post ramscar.wordpress.com/2015/10/26/…

Even if they might not like it, you may want to know the information.

It is possible that some bosses would object to this course of action if asked, but would be happy with it if they didn't know. My concern in that case would be, what if the boss finds out some other way? That's not a risk I would want to take, but of course, different people are comfortable with different levels of risk.

To me the phrasing "don't admit" implies lying... I wouldn't use it to mean "don't volunteer". I guess that's just a difference in how we use these phrases, but it might confuse other people as well. Anyway, I consider lies by omission to also be lies. Also, if I thought my boss would consider me to be a "lazy bum" if she learned about this, I'm not sure I would do it. It seems risky, since she might find out even without me telling her. I'm not sure why she would consider it lazy though... it seems smart to me.

I'd upvote if it weren't for the "don't admit to it". Why is it necessary to lie about this?
