Increasingly more shops are extending their working hours throughout the week in some countries. While this development can be negative given extra expenses involved, I personally see it an overall change for the better.
The major concern resulting from a modification to running hours of shops would be related to finance. It is true that longer availability, in some cases 24/7, increases overheads—including utilities and salaries—significantly, which may not be justified given a lower volume of customers at night. This is highly likely to affect the financial health of businesses, since extra expenses engender reductions in profits, making it difficult to function properly and explore expansion options.
Nevertheless, I consider extended availability of shops to be a favorable development. This is firstly because of the convenience created for customers, who, due to rising living costs, have to work overtime or take multiple jobs to make a living. These people, more often than not, complete their shifts late at night, so they would like to do grocery shopping or dine out. Consequently, this convenience creates opportunities for them to enjoy their weekends by spending quality time with family members or doing hobbies.
Yet another beneficial impact of this development would be employment opportunities for local people. Prolonging working hours necessitates hiring more people for evening and, if needed, night shifts. If many such shops decide to implement this policy, then that region can experience a reduction in unemployment levels, thereby improving the quality of life for store employees.
In conclusion, although higher running expenses can be the primary downside of shops remaining open for longer, I would argue that it is far outweighed by the convenience it creates for shoppers and the improved employment opportunities for local residents.
