Everyone is responsible, do not set one person as an outlier. Everyone is accountable. It is a cultural thing. Safety.
How do you create a culture?
Work as equals
Managers help out and "get their hands dirty"
Encourage others to call their coworkers if they don't show up
Outside of the job place
Give regular reviews where you focus on improvement not hostile negatives
Have regular meetings where you give productive and useful tools to succeed
Play favorites selectively
Recognize the leaders on your staff and encourage them to motivate others
Give them more authority or responsibility
Mentor your staff
Foster an apprenticeship system where new members are brought into the fold by an older more experienced team member
Say hi and learn about everyone else
Be consistent and clear with rules and discipline. Make it clear and transparent
