The supreme court's power is limited in that:

1. they serve for life
2. their decisions can be overturned by future supreme court justices
3. their rulings can be struck down by presidential veto
4. constitutional amendments can be passed by congress

2. their decisions can be overturned by future Supreme Court justices.

Explanation:

The Supreme Court is the highest court in the US, and its rulings establish precedents for other courts to follow. No lower court, nor the Congress or the president are allowed to change, reject, ignore or overturn a Supreme Court decision. The most usual way of overturning Supreme Court rulings is through the decision of a later Supreme Court. For example, Brown v. Board of Education definitely overruled the resolution made in Plessy v. Ferguson, 58 years before.

it all depends on how long the hours are. i think they wouldn't approve of it. in my opinion.
