the same casual mind-set
The debate over uniforms in public schools encompasses many larger issues than simply what children should wear to school. It touches on issues of school improvement, freedom of expression and the “culture wars.” It’s no wonder the debate rages on.
A new trend is the mounting pressure to establish dress codes for teachers. Apparently the same casual mind-set toward revealing outfits is cropping up in the ranks of our teachers.
Regarding the part of the same casual mind-set, what does "casual" mean exactly?
Of course, the word "casual" has various meanings, but it seems like to have some negative connotation here.
If possible, could you give me some synonyms for this "Casual" Thank you very much :)
