Hi there Ryo! Here is my version of the diary, hope you like it! I think that companies can increase staff productivity, by making them leave the office on time every day. By working overtime, worker’s productivity may increase in the short run. But in the long run, continuing to work overtime can make one get sick or even become depressed -leading to a longer rest. This leads to not only a decrease in productivity at work, but also a hard experience in life for the employees. A ‘healthy work environment’, is the best way to increase our productivity in the long term. This can be done by leaving on time every day, in order to establish effective staff productivity. I think that companies should make various efforts to realize it.
