While there are several aspects of good workplace behavior that contribute to positive relationships, the option that most closely aligns with calling in sick only when truly sick is C. Having a good attitude.
Here's why:
Carrying your own weight (A) does demonstrate responsibility and helps the team function smoothly, but it doesn't directly relate to taking sick leave ethically.
Getting to know others on your work team (B) fosters good working relationships, but it's not directly connected to sick leave usage.
Being cooperative (D) implies working well with others, which is valuable, but it again doesn't specifically address using sick leave responsibly.
Having a good attitude (C) encompasses being responsible, considerate, and reliable, which includes using your sick leave appropriately. Taking a sick day when truly unwell prevents spreading illness to colleagues and demonstrates respect for their health and well-being. It also shows you are trustworthy and prioritize a healthy work environment.
Therefore, while all the listed behaviors contribute to positive working relationships, C. Having a good attitude most directly relates to the responsible use of sick leave and its impact on building trust and respect among colleagues.
