A co-worker of mine is on his last strike, because of slacking. He is generally a good employee, and good person, but he is often to get distracted into surfing internet when he got 'nothing' to do at work.
Me and this coworker are pretty close friend at work, and I'd like to support him so he won't get fired. We are in the same room, with 2 other colleagues. Sometimes I jokingly reminded him when he opened some random websites, but there's no guarantee he won't be doing that again.
What else I can do to support him? I'm aiming for a general behavior change, and in short term to find him more work to do so he doesn't have the time to surf random sites.
Note: I'm neither his superior nor more senior than him, but generally he respects me when I give some advice.
