Employees at NT Shop appreciate the supportive and helpful colleagues, as well as the opportunities to learn customer service skills, deal with suppliers, and manage staff. They also strive to maintain a positive attitude when interacting with customers and colleagues. However, some potential challenges include concerns about low salaries, long working hours, the number of rules and policies employees need to follow, a lack of career development programs for shop assistants and supervisors, rest periods that are not long enough leading to fatigue, and low staffing levels.
