According to this source, Poland will gradually forbid commerce on Sundays:
Poland’s ruling party approved a law that will gradually impose a ban on Sunday shopping, meeting the demand of its conservative Catholic supporters with a measure that risks undermining economic growth and hitting corporate profits and real-estate investors.
According to this article, EU regulations deal more with ensuring weekly rest periods rather than ensuring a free Sunday:
There are no specific EU regulations regarding weekend work. The 1993 Working Time Directive determined that the minimum weekly rest period ‘shall, in principle, include Sunday’. In 1996, however, the European Court of Justice annulled this provision by ruling that:
the Council has failed to explain why Sunday, as a weekly rest day, is more closely connected with the health and safety of workers than any other day of the week.
The 2003 Working Time Directive does not refer to any specific day in relation to weekly rest periods or any other aspect of working time. Article 2 of the European Social Charter says that Member States should agree:
to ensure a weekly rest period which shall, as far as possible, coincide with the day recognised by tradition or custom in the country or region concerned as a day of rest.
From the economic point of view, this seems to have a negative effect upon tourism and those who can mostly work during the week-ends (e.g. students).
Question: Why do some countries forbid working on Sunday rather than strictly regulating it?
By strict regulation I am thinking about something resembling my own country's regulation, that can be summed up very roughly as:
- normal working schedule is 40h/week
- extended (on request by worker or company) working schedule can be up to 48h/week
- working on any week-end day is paid (almost) double (or a free day + normal payment)
- working on any public holiday is paid double and an extra free day
So, working on Sundays is not forbidden, but companies cannot abuse it due to higher costs associated with it.
