The strictness or looseness of the team can not be reflected by shouting slogans and not being late. The key is to keep the team goals consistent with the individual goals of the members, so that everyone can have a relaxed and harmonious environment and work hard. If it's just a formality, a fine won't solve the problem. You can face this problem, which shows that you have the motivation to make progress. I suggest you read management books, which is good for your future growth.
