No, just avert your eyes in the future
Yes, that's unacceptable
PS He sounds creepy. Who watches porn in public? Yuck.
If co-workers are intimidated enough not to enter a work area, then this is a problem and he has created a hostile work environment. I would leave an anonomous note stating that his porn viewing while on company time is against company policy and a theft of company money as he's doing it when he should be working (i.e. he's getting paid to watch porn) and if it doesn't stop he will be reported to HR. If it continues, then report his *ss! Shasta, you must also be prepared that your HR person may also prohibit any use of company computers usage outside of the normal work things off limits, so you may have to stop using yours to come here to the SKMB. It sucks, but what's good for the goose............ Us SKMB members may not be porn stars (I'm not speaking for everyone), but it is outside of normal work usage. My company would've fired this guys butt a long time ago.
...but some of us like Star Trek.....Us SKMB members may not be porn stars
I'm one of those weirdo's who thinks when at work you should be working. Not on e-bay, or Facebook, or surfing the net. I also don't think you should be having texting conversations while at work. (I absolutely hate having to wait while an employee continues personal texts while I - the customer - wait.)
In my opinion, this equates to theft of time.....and time is money.
