**Some context:** My coworker and me are foreigners working in Japan as IT developers

Our team do work from home 2-3 days ) week

This coworker is working fully from home (Too far from workspace)

**Issue:**

I recently discovered that one of my coworker is pushing himself way too much (Working lot of (partially hiden) overtime, skipping or rushing lunchs, not taking day off when sick, etc...

It took time to realize because he works fully remotely, and partially hide his real working time

I realized because some references he said, and some of his git commit times

**What I tried:**

- Telling him that we work as a team and that we can all support each other
That we can talk openly when we need to adjust timing / deadline / resources

- Telling him that taking breaks and proper sleep and lunch is helping us to work better

- Suggesting he could take day off when he told he was sick and that we can follow-up / continue on his tasks

- Warn my Scrum Master twice
Thus, my SM sync with my coworker

But even after all that it seems the situation did not changed...

This coworker will easily say he think he is not capable etc, but if I try to ask more details het settle back

I wonder what (other) approach would be good... ?
