Narrative:

During initial climb out le slat EICAS message with master caution switch and aural occurred right after retracting flaps. These messages persisted intermittently along with both flap indicator needles being stuck at half until we were at 15;000 feet and had been in a hold for a while talking to maintenance and operations on the radio. Crew actions and considerations: the first officer (first officer) continued to fly the airplane - it handled relatively normally other than the indications and caution notifications. Captain called radio for a phone patch to company; and first officer took ATC comms. Coordinated to ask for holding so that we could maintain within radio coverage for the phone patch. ATC directed at hold at 15;000 feet at zzzzz intersection. Le slat assym/disagree EICAS messages continued to display intermittently while we ran QRH procedures; communicated situation with dispatch; and calculated fuel. Roughly 20 minutes into holding; the le slat issues cleared. Company concluded that the fuel at [our destination] would not be sufficient; so we planned to return to ZZZ after holding to burn off enough fuel to land under the max gross landing weight. ATC asked how much time in the hold would be necessary and the first officer informed them that we would be returning to the field and requesting the longest runway available. The captain ended the phone patch; returned to speaking with ATC; and they gave us a new hold until our estimate for the arrival. We began the arrival shortly after the planned efc [expect further clearance] time; and were assigned the RNAV approach. While setting up for the arrival; the autobrakes would not engage. The arrival and approach occurred with no further abnormalities. Upon landing; ATC advised the emergency vehicles were standing by. They escorted us to our gate. We wrote the slat issue and autobrakes up in the logbook and gave maintenance all available information. It would be helpful is dispatch was able to quickly calculate required fuel numbers at any point in the flight given actual weights.

Title: B767 flight crew reported a delay in receiving fuel requirements from Dispatch following a post-takeoff LE SLAT ASSYM/DISAGREE alert.

Narrative: During initial climb out LE SLAT EICAS message with Master Caution switch and aural occurred right after retracting flaps. These messages persisted intermittently along with both flap indicator needles being stuck at half until we were at 15;000 feet and had been in a hold for a while talking to maintenance and operations on the radio. Crew actions and considerations: The FO (First Officer) continued to fly the airplane - it handled relatively normally other than the indications and caution notifications. Captain called Radio for a phone patch to company; and FO took ATC Comms. Coordinated to ask for holding so that we could maintain within radio coverage for the phone patch. ATC directed at hold at 15;000 feet at ZZZZZ intersection. LE SLAT ASSYM/DISAGREE EICAS messages continued to display intermittently while we ran QRH procedures; communicated situation with dispatch; and calculated fuel.
