Yesterday at work, I was finishing my morning espresso when my phone rang and in reaching for it, accidentally spilled some of the drink on the computer keyboard. I immediately unplugged the equipment and used paper towels to absorb as much of the liquid as possible, especially between the keys. So far, no damage has manifested itself, but I know damage to computers due to spilled liquids may not be immediate.
I am well liked at my company and have a good relationship with my peers and manager alike. My performance according to my most recent evaluation is excellent. My manager is very personable.
I feel terrible for my actions. I accept responsibility for any damage that might appear. My sloppiness in this case might have caused loss to the company and in hindsight, trying to do both actions was definitely not a good idea. I tried to salvage the situation to the best of my ability, but am uncertain about how my boss will respond / repercussions that may follow.
Should I inform my manager of this incident and if so, how can I do so most constructively?
