Punctuality and Flexibility

Nowadays, an alternative system to rigorous observance of punctuality seems inevitable as the conflict between people's demand for punctuality and the various handicaps factors preventing them from punctuality (you could also say from being punctual or from being on time) grows tense. It is intelligible understandable (intelligible does not express the meaning you want here and in this context means "able to be understood audibly"). A better choice is that companies require their staff to be punctual (I am not sure what you mean here. Maybe you mean It is a good choice for companies to require their staff to be punctual), but a company being ruthless to its employees on (I woud say concerning) punctuality is likely to disappoint them. for After all, we are human beings, and there are somethings out of our control like an accident on the way to work or an emergency call from a loved one. From this point of view, to maintain the loyalty of the staff, companies ought to take the initiative to make a change.
Above all, a flexible time system may become the best choice for some companies to substitute the set time system. However, it doesn't mean that the staff can choose when to go to work unbuttonedly without restriction. Of course the majority of their working time is overlapped so that they can conduct the work that needs corporations cooperation. The flexible time system just suggests a compatible mode for those who fall into unexpected, unavoidable incidents. Compared to the rigid observance of working schedule, the flexible time system allow employees to come to work not that less regularly thus work in a less stressful circumstance. Employers will benefit as well because in a sense, employees would be truly grateful heartfeltly which contributes to their positiveness and efficiency at work. By and large, it takes mutual repects and understandings from both parts to create a harmonious working environment and finally make a big fortune.
In addition, there are other approaches to change such as postponing the working hours to avoid the rush hours or houlding a video meeting if someone fails is not able to be present. Anyway, the main point is these suggestions would to make the company hummanized, thoughtful, and appealing to the employees.

Nice point! I hope this helps!
