1) They were attacked repeatedly. See Judges ch.4, 6, and 11 (for example).
2) There were some of the Israelites who dabbled in the idolatry of the neighboring nations, thus putting the future of Judaism at risk. See Judges ch.2.
The Israelite Tribes were organized into a loose confederacy during the Era of the Judges and while they generally retained friendly relations between each other, they did not rise to each others' defense naturally in response to foreign threats. As long as enemies made sure to pillage only one tribe, they usually could not expect a unified Israelite response. The anomalies during that period occurred when the individual Judges were able to convince several tribes to pool resources and attack the pillaging neighbors. At this period in history, thankfully, the Israelites did not have to contend with massive empires like Egypt or Assyria which could have easily overrun the Israelite confederacy (assuming no Divine miracles).

The books of Judges cover a period of about 325 years from around 1380 to 1050 BCE, focusing on the time of the Judges in Israel. The book of Ruth, on the other hand, is set during the time of the Judges but specifically focuses on the story of Ruth and her mother-in-law Naomi during a shorter period of time.

If you're asking about the Book of Judges, no distinction is made concerning major or minor. Rather, some of the Judges are better-known, because their leadership is narrated in greater detail, while other Judges are mentioned only briefly (Judges 12:8-15). This does not mean that they were minor in any way, but simply that there was quiet during their lifetime. See also:More about the Judges
Judges do get vacations. In fact, some judges in the Federal system only sit for a specific number of months during the year. When they aren't actively hearing cases they are working on cases that have been accepted for appeal and they can take time off.
