Drucker began his journalistic career as a general reporter, and later on a real-estate and infrastructure reporter in Maariv newspaper. In 1997 he was promoted to be the newspaper's chief political reporter. In 1998 he became the political and diplomatic correspondent for Galei Tzahal (Israel's Army Radio), where he also occasionally hosted the daily "Ma Bo'er" (What's Hot) news broadcast.
In the 2002/3 academic year Drucker was a Nieman Fellow at Harvard University.
After returning to Israel, Drucker became Channel 10's political commentator. He was later the co-presenter of the Channel's Friday evening news program together with Ofer Shelah. In 2009 he became the host of Hamakor ("the Source"), the Channel's investigative reporting magazine. He co-hosted the show together with Shelah, who was replaced by Mickey Rosenthal when Shelah decided to join politics. Rosenthal himself later joined Israeli politics and was replaced as Drucker's co-host by Razi Barkai. Both Shelah and Rosenthal were elected to the Knesset in the 2013 elections.
Drucker is responsible for unearthing several high-profile scandals in Israeli politics, that were a result of his investigations.
Three weeks before the 2006 elections, he exposed the "Omri Diary", the schedule of Omri Sharon, son of Israel's late Prime-Minister Ariel Sharon and a Knesset member himself. The papers detailed political appointments orchestrated by Sharon jr.
On June 15, 2007, three days after the primary elections for chairperson of the Israeli Labor Party, Drucker aired candid camera footage showing the faking of ballots results, a report which led to a police investigation.
Another police investigation was the result of his publication of leaked documents from Ehud Olmert's office as Israel's Prime Minister, documenting various promises to member's of the Likud convention.
In 2008 Drucker published a series of reports on travels of Benjamin Netanyahu as a Knesset member, with his wife to London. According to the reports, these travels were paid for by private donors and included ostentatious accommodation, and were not properly approved of by the Knesset Ethics' committee. PM associates accused Drucker of applying a double-standard, and the Netanyahus filed a libel suit against Drucker, which they later withdrew. The scandal is known in Israeli politics as "Bibi tours" (Bibi is the Nickname for Netanyahu). It was later reported that Netanyahu aides tied government willingness to postpone collection of Channel 10 debts to the state, which threatened its existence, to a demand to fire Drucker. In January 2015 Drucker published a draft of the State Comptroller's report on the matter, which according to the publication raises suspicion of compromised integrity.
In 2014 Drucker ran a series of investigative reports on the Jewish National Fund a non-profit organization owning 13% of total land in Israel, documenting questionable agreements with politicians and media outlets and politically motivated allocations of major sums to projects with allegedly little connection the organizations declared goals.
In October and November 2016 Drucker published a series of investigative reports related to Israel's PM, Benjamin Netanyahu. The one that drew the most attention argued that Netanyahu's personal lawyer and second cousin, David Shimron, represented a German submarine's manufacturer in a multi-millions dollar deal with Israel, alleging possible conflict of interest. Another report alleged that Netanyahu's son, Yair Netnayahu, received valuable gifts from Australian Billionaire James Packer, and triggered a police investigation. Netanyahu responded with fierceful attacks on Drucker in his personal Facebook account, accusing him of "morbid and obsessive pursuit of the prime minister" and his family, and framing his channel 10 as "radical left-wing". The affair and the row it caused in social media brought many in Israeli media to raise concerns regarding Drucker's safety.
In 2004 Drucker founded the Movement for Freedom of Information in Israel. He served as its chairman through December 2016.
Drucker is the author of two books: Harakiri about the period of Ehud Barak's government, and Boomerang, which he wrote together with Ofer Shelah, about "the failure of Israeli leadership during the second Intifada".2008 OMETZ award (Citizens for Good Governance and Social Justice).
