When asked about the bottle, Craig went into a bathroom and shut the door. She left the school premises, but later returned, and got involved in a confrontation with a junior teacher, which involved swearing in front of students.
As the school had already showed compassion after another incident with alcohol,
it decided this was not acceptable. Craig resigned. She told the tribunal she suffered stress and depression, and at the time had not been sleeping.
She said she'd picked up the bottle of vodka and some lasagna at lunchtime to take to a friend's house. She had not drunk the alcohol, she said.
The tribunal said the behaviour, coupled with a 2013 conviction for drunk driving, compounded the "seriousness of the misconduct".
As such, it did not grant name suppression saying: "It is clearly time for this teacher to face up and deal with her alcohol problem".
Her teaching licence was suspended for 18 months, unless Craig could prove earlier that she was fit to return to teaching. She was seeking treatment, the decision said.
