You can activate on up to two computers. They just can't be used at the same time. So one activation at home and one at work.
Both can be used commercially. If you get up from your seat and let another worker use your Photoshop, that would be fine.
I mean i have 4 computers at my work. For each i will buy that offer i mentioned. So each computer will use its own licence.
The question is that is it legal to use an Individual Membership Membership plans: Pricing and subscriptions | Adobe Creative Cloud for commercial use?
Well, seems like the Photography Program is one to a customer. You could call customer service to confirm,but your employees would more than likely have to have their own account. You could reimburse them for that expense, I suppose.
