Now this part I can't really agree with. Holodeck isn't a tool that is issued by Starfleet with the goal to do your job. It's a recreation device that people aboard Enterprise have access to. So it would be more like discovering that your collegue is late for work because he obsessively visits strip clubs. In Barclay's case: strip clubs that allow you to put super-realistic masks of your collegues from work onto the strippers![]()
The holodecks are Starfleet property, though, and are made available to Starfleet employees for recreative purposes. So in your analogy, those strip clubs would have to be Starfleet property as well.
Also, I believe that holodecks have a double role and that they are also used for training (i.e. work-related) purposes. After all, they're far too useful to not use them for that as well. We see that sometimes, too. Worf's Calisthenics program, Geordi running engine room simulations, Deanna taking the bridge officer test on it. It's just that we see them more often in a recreative context.
