How do you deal with major distractions at work?

Put on my noise cancelling headphones.

It depends on what the distraction is. Major distraction sounds more like an urgent matter and should be address accordingly. Staying calm is necessary for thinking straight and keep your composure helps for getting back to work promptly after distraction has ended.

wear a hoodie and use earphones, block the bullshit

With frustration. The Continuous Improvement and Safety Conditions/Behaviors are a MAJOR DISTRACTION. I cannot focus on my work by being FORCED to do those programs

Depends on the distraction, and if it can be eliminated.

I push through it and continue to do my job.

Do my best to ignore whatever or whoever is distracting me.

I work from home, and I have tons of potential distractions with no one watching me. Focusing can be a challenge sometimes. I use many strategies, like software the restrict the usage of websites and applications (FocusMe for Windows, AppBlock for Android), and I try to use the Pomodoro technique not only to help me focusing, but also to avoid hyper-focusing in a single task. I also avoid replying instantly to email, setting a reminder to review email by the middle and the end of the day. Music can be useful to "warm up" when starting boring tasks, but it can also be a distraction, so I may turn it off after a while. I have learned to avoid YouTube as a source of music, and I prefer Pandora, which provides a decent selection of music based on my tastes and mood.

One positive way is to focused on the expected deliverable of your day to day task and the satisfactory feeling that emanates from that. Exhibit an insatiable intellectual curiosity on operative mechanisms of things outside your job scope but are inextricably linked with yours. Engage with colleagues, however, and talk less about things that are unrelated to the work that you do... because that could be a totally huge distraction. I usually have my voicemail activated and limit my call activities to my immediate family and Boss. On a lighter note, and equally important is to ensure things are positive at home so that the vibrant positive energy generated that ensues can be transplanted from the home to the work space.

You just get use to it & keep on going, nothing you can do.

Prioritize and focus on my own work

If there's a personal issue distracting me so much that I can't work, I'll take a personal day to address the issue. If it's something like my phone going off, I'll just turn off the phone after verifying there's no emergency. If I'm struggling with being focused, I'll try switching tasks or taking a walk, or brainstorming with a co-worker. If someone in the office is distracting me indirectly (being loud, etc.) I'll put on my headphones and use music to drown them out. If I'm distracted because people keep stopping by my desk, sometimes the headphones dissuade them or I'll find somewhere else to sit and work for a bit.

Bring up the issue at the next retrospective

We sit in an open concept/bullpen area. I play music over my headset and have a fan going at all times.

Yes, open seating... it's just a cost saver, not productive.

Ignore them since my company could care less about debilatating work environments.

Tune them out or go in another room.

Earbuds and music. Can focus more when I'm in my own zone.
