Whether your job is Temporary/ Contract, Temp-to-Hire, Direct-Hire, remote or on-site, calling out of work from time to time is inevitable. You might need to miss work for family emergencies, medical issues, scheduled appointments, etc. Managers understand that their employees are human and life happens, expectedly and unexpectedly. The best thing to do is respectfully and briefly inform your supervisor of why you need to take time off. You don’t need to go into detail, legally there are federal limitations to what an employer can ask when you call out sick, unless you’re covered by the Americans with Disabilities Act.
